General description
The TEA1620P is a Switched Mode Power Supply (SMPS) controller IC that operates
directly from the rectified universal mains. It is implemented in the high voltage EZ-HVTM
SOI process, combined with a low voltage BICMOS process.
The device includes a high voltage power switch and a circuit for start-up directly from the
rectified mains voltage. A dedicated circuit for valley switching is built in, which makes a
very efficient slim-line electronic power-plug concept possible.
In its most basic version of application, the TEA1620P acts as a voltage source. Here, no
additional secondary electronics are required. A combined voltage and current source can
be realized with minimum costs for external components. Implementation of the
TEA1620P renders an efficient and low cost power supply system.

7.2 Pin description

Functional description
The TEA1620P is the heart of a compact flyback converter, with the IC placed at the
primary side. The auxiliary winding of the transformer can be used for indirect feedback to
control the isolated output. This additional winding also powers the IC. A more accurate
control of the output voltage and/or current can be implemented with an additional
secondary sensing circuit and optocoupler feedback.
The TEA1620P uses voltage mode control. The frequency is determined by the maximum
transformer demagnetizing time and the time of the oscillator. In the first case, the
converter operates in the Self Oscillating Power Supply (SOPS) mode. In the latter case, it
operates at a constant frequency, which can be adjusted with external components R
RC
and C
RC
. This mode is called Pulse Width Modulation (PWM). Furthermore, a primary
stroke is started only in a valley of the secondary ringing. This valley switching principle
minimizes capacitive switch-on losses.
8.1 Start-up and undervoltage lock-out
Initially, the IC is self supplying from the rectified mains voltage. The IC starts switching as
soon as the voltage on pin V
CC
passes the V
CC(start)
level. The supply is taken over by the
auxiliary winding of the transformer as soon as V
CC
is high enough and the supply from
the line is stopped for high efficiency operation.
As soon as the voltage on pin V
CC
drops below the V
CC(stop)
level, the IC stops switching
and restarts from the rectified mains voltage.
8.2 Oscillator
The frequency of the oscillator is set by the external resistor and capacitor on pin RC. The
external capacitor is charged rapidly to the V
RC(max)
level and, starting from a new primary
stroke, it discharges to the V
RC(min)
level. Because the discharge is exponential, the
relative sensitivity of the duty factor to the regulation voltage at low duty factor is almost
equal to the sensitivity at high duty factors. This results in a more constant gain over the
duty factor range compared to PWM systems with a linear sawtooth oscillator. Stable
operation at low duty factors is easily realized. For high efficiency, the frequency is
reduced as soon as the duty factor drops below a certain value. This is accomplished by
increasing the oscillator charge time.

To ensure that the capacitor can be charged within the charge time, the value of the
oscillator capacitor should be limited to approximately 1 nF.
8.3 Duty factor control
The duty factor is controlled by the internal regulation voltage and the oscillator signal on
pin RC. The internal regulation voltage is equal to the external regulation voltage (minus
2.5 V) multiplied by the gain of the error amplifier (typical 20 dB or 10
).
The minimum duty factor of the switched mode power supply is 0 %. The maximum duty
factor is set to 75 % (typical value at 100 kHz oscillation frequency).
8.4 Valley switching
A new cycle is started at the primary stroke when the switch is switched on (see
Figure 3
).
After a certain time (determined by the RC oscillator voltage and the internal regulation
level), the switch is turned off and the secondary stroke starts. The internal regulation
level is determined by the voltage on pin REG. After the secondary stroke, the drain
voltage shows an oscillation with a frequency of approximately
Where:
L
p
is the primary self inductance on the drain node
C
p
is the parasitic capacitance on the drain node.
As soon as the oscillator voltage is high again and the secondary stroke has ended, the
circuit waits for a low drain voltage before starting a new primary stroke.
The primary stroke starts some time before the actual valley at low ringing frequencies,
and some time after the actual valley at high ringing frequencies.
Figure 4
shows a typical
curve for a reflected voltage N
V
o
of 80 V. This voltage is the output voltage V
o
(see
Figure 5
) transferred to the primary side of the transformer with the factor N (determined
by the turns ratio of the transformer).
Figure 4
shows that the system switches exactly at
minimum drain voltage for ringing frequencies of 480 kHz, thus reducing the switch-on
losses to a minimum. At 200 kHz, the next primary stroke is started at 33
before the
valley. The switch-on losses are still reduced significantly.

8.5 Demagnetization
The system operates in discontinuous conduction mode all the time. As long as the
secondary stroke has not ended, the oscillator will not start a new primary stroke. During
the suppression time t
suppr
, demagnetization recognition is suppressed. This suppression
may be necessary in applications where the transformer has a large leakage inductance
and at low output voltages.
8.6 Protections
8.6.1 Overcurrent protection
The cycle-by-cycle peak drain current limit circuit uses the external source resistor R
I
(see
Figure 5
) to measure the current. The circuit is activated after the leading edge blanking
time t
leb
. The protection circuit limits the source voltage to V
source(max)
, and thus limits the
primary peak current.
8.6.2 Short winding protection
The short winding protection circuit is also activated after the leading edge blanking time.
If the source voltage exceeds the short winding protection voltage V
swp
, the TEA1620P
stops switching. Only a power-on reset will restart normal operation. The short winding
protection also protects in case of a secondary diode short circuit.
8.6.3 Overtemperature protection
An accurate temperature protection is provided in the TEA1620P. When the junction
temperature exceeds the thermal shutdown temperature, the IC stops switching. During
thermal protection, the IC current is lowered to the start-up current. The IC continues
normal operation as soon as the overtemperature situation has disappeared.
8.6.4 Overvoltage protection
Overvoltage protection can be achieved in the application by pulling pin REG above its
normal operation level, or by keeping the level of pin AUX above V
demag
. The current
primary stroke is terminated immediately, and no new primary stroke is started until the
voltage on pin REG drops to its normal operation level. Pin REG has an internal clamp.
The current feed into pin REG must be limited.
8.7 Characteristics of the complete power-plug
8.7.1 Input
The input voltage range comprises the universal AC mains from 80 V to 276 V.
8.7.2 Accuracy
The accuracy of the complete converter, functioning as a voltage source with primary
sensing, is approximately 8 % (mainly dependent on the transformer coupling). The
accuracy with secondary sensing is defined by the accuracy of the external components.
For safety requirements in case of optocoupler feedback loss, the primary sensing
remains active when an overvoltage circuit is connected.

8.7.3 Efficiency
An efficiency of 75 % at maximum output power can be achieved for a complete converter
designed for universal mains.
8.7.4 Ripple
A minimum ripple is obtained in a system designed for a maximum duty factor of 50 %
under normal operating conditions, and a minimized dead time. The magnitude of the
ripple in the output voltage is determined by the frequency and duty factor of the
converter, the output current level, and the value and ESR of the output capacitor.

15. Soldering
15.1 Introduction to soldering through-hole mount packages
This text gives a brief insight to wave, dip and manual soldering. A more in-depth account
of soldering ICs can be found in our
Data Handbook IC26; Integrated Circuit Packages
(document order number 9398 652 90011).
Wave soldering is the preferred method for mounting of through-hole mount IC packages
on a printed-circuit board.
15.2 Soldering by dipping or by solder wave
Driven by legislation and environmental forces the worldwide use of lead-free solder
pastes is increasing. Typical dwell time of the leads in the wave ranges from
3 to 4 seconds at 250
C or 265
C, depending on solder material applied, SnPb or
Pb-free respectively.
The total contact time of successive solder waves must not exceed 5 seconds.
The device may be mounted up to the seating plane, but the temperature of the plastic
body must not exceed the specified maximum storage temperature (T
stg(max)
). If the
printed-circuit board has been pre-heated, forced cooling may be necessary immediately
after soldering to keep the temperature within the permissible limit.
15.3 Manual soldering
Apply the soldering iron (24 V or less) to the lead(s) of the package, either below the
seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is
less than 300
