Ground. SenseFET source terminal on primary side and internal controller ground.
Power Supply. The internal protection circuit disables PWM output as long as V
OVP trigger point.
Feedback. The signal from the external compensation circuit is fed into this pin. The PWM duty
cycle is determined in response to the signal on this pin and the internal current-sense signal.
Line-Voltage Detection. The line-voltage detection is used for brownout protection with
hysteresis and constant output power limit over universal AC input range. This pin has additional
protections that are pull-HIGH latch and pull-LOW auto recovery, depending on the application.
No Connection. FSBH0F70A_F116
Startup. For startup, this pin is pulled HIGH to the line input or bulk capacitor via resistors.
SenseFET Drain. High-voltage power SenseFET drain connection.
SenseFET Drain. High-voltage power SenseFET drain connection.
SenseFET Drain. High-voltage power SenseFET drain connection.
