Pin Definitions
Pin Number
Pin Name
Pin Function Description
1Drain
High voltage power SenseFET drain. This pin is designed to drive the
transformer directly and is capable of switching a maximum of 650V and 4A.
2
GND
This pin is the control ground and the SenseFET source.
3Vcc
Vcc is regulated at 22V during the normal mode by the internal Vcc feedback
loop. During the off mode Vcc fluctuates between 11V and 12V.
4
Feedback
This pin is connected to the inverting input of the PWM comparator through two
diodes and a resistor divider. For stable operation, a capacitor should be placed
between this pin and GND.
5
Soft Start &
Sync
This pin performs the soft start operation and detects the external sync signal.
