OVERLOAD AND SHORT-CIRCUIT CONTROL
DESCRIPTION
The VIPer53 combines in the same package an
enhanced current mode PWM controller with a
high voltage MDMesh Power Mosfet. Typical
applications cover off line power supplies with a
secondary power capability ranging up to 30W in
wide range input voltage or 50W in single
European voltage range and DIP-8 package, with
the following benefits:
Overload and short circuit controlled by
feedback monitoring and delayed device reset.
Efficient standby mode by enhanced pulse
skipping.
Primary regulation or secondary loop failure
protection through high gain error amplifier.

PIN FUNCTION
CURRENT AND VOLTAGE CONVENTIONS

ORDER CODES
Name
Function
V
DD
Power supply of the control circuits. Also provides the charging current of the external capacitor during
start-up. The functions of this pin are managed by four threshold voltages:
- V
DDon
: Voltage value at which the device starts switching (Typically 11.5 V).
- V
DDoff
: Voltage value at which the device stops switching (Typically 8.4 V).
- V
DDreg
: Regulation voltage point when working in primary feedback (Trimmed to 15 V).
- V
DDovp
: Triggering voltage of the overvoltage protection (Trimmed to 18 V).
SOURCE
Power Mosfet source and circuit ground reference.
DRAIN
Power Mosfet drain. Also used by the internal high voltage current source during the start-up phase, for
charging the external V
DD
capacitor.
COMP
Input of the current mode structure, and output of the internal error amplifier. Allows the setting of the
dynamic characteristic of the converter through an external passive network. Useful voltage range
extends from 0.5 V to 4.5 V. The Power Mosfet is always off below 0.5 V, and the overload protection is
triggered if the voltage exceeds 4.35V. This action is delayed by the timing capacitor connected to the
TOVL pin.
TOVL
Allows the connection of an external capacitor for delaying the overload protection, which is triggered by
a voltage on the COMP pin higher than 4.35V.
OSC
Allows the setting of the switching frequency through an external Rt-Ct network.

ABSOLUTE MAXIMUM RATINGS
Note: 1. In order to improve the ruggedness of the device versus eventual drain overvoltages, a resistance of 1 k
should be inserted in
series with the TOVL pin.
