DESCRIPTION
The TDA1170N is a monolithic integrated circuit in
a 12-lead quad in-line plastic package. It is in-
tended for use in black and white and colour TV
receivers. Low-noise makes this device particularly
suitable for use in monitors. The functions incorpo-
rated are : synchronization circuit, oscillator and
ramp generator, high power gain amplifier, flyback
generator, voltage regulator.

During soldering the tab temperature must not
exceed 260
C and the soldering time must not be
longer than 12 seconds.
The external heatsink or printed circuit copper area
must be connected to electrical ground.
The junction to ambient thermal resistance can be
reduced by soldering the tabs to a suitable copper
area of the printed circuit board (fig. 5) or to an
external heatsink (fig. 6).

ble power P

side "e" of two equal square copper areas having
a thicknessof 35
