Name
Description
1
GND
Ground
. SenseFET source terminal on primary side and internal controller ground.
2
VDD
Power Supply
. The internal protection circuit disables PWM output as long as VDD exceeds the
OVP trigger point.
3
FB
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.
4
VIN
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.
NC
No Connection
. FSBH0F70A_F116
5
HV
Startup
. For startup, this pin is pulled HIGH to the line input or bulk capacitor via resistors.
6
Drain
SenseFET Drain
. High-voltage power SenseFET drain connection.
7
Drain
SenseFET Drain
. High-voltage power SenseFET drain connection.
8
Drain
SenseFET Drain
. High-voltage power SenseFET drain connection.
