External Synchronization with Primary-Control AC/DC Converter (cont.)
(2) Combination with a forward AC/DC converter (simplified schematic)
This circuit illustrates the combination of the HA16114/120 with a forward AC/DC converter. The
HA16114/120 synchronizes with the falling edge of the external sync signal, so with a forward
transformer, the sync pulses must be inverted. In the diagram, this is done by an external circuit
consisting of the following components:
Q:
R

and R

:
ZD:
Transistor for inverting the pulses. Use a small-signal transistor.
These resistors form a voltage divider for driving the base of transistor Q. R
2
also provides
a path for base discharge, so that the transistor can turn off quickly.
Load resistor for transistor Q.
Zener diode for protecting the SYNC pin.
