Pin Definitions
Pin #
Name
Description
1
VIN
Line-voltage detection. The line-voltage detection is used for brownout protection with hysteresis.
Constant output power limit over universal AC input range is also achieved using this VIN pin. It
is suggested to add a low-pass filter to filter out line ripple on the bulk capacitor. Pulling VIN
HIGH also triggers auto-restart protection.
2
FB
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 current-sense signal on the SENSE pin.
3
SENSE
Current sense. The sensed voltage is used for peak-current-mode control and cycle-by-cycle
current limiting.
4
GND
Ground
5
GATE
The totem-pole output driver. Soft-driving waveform is implemented for improved EMI.
6
VDD
Power supply. The internal protection circuit disables PWM output as long as VDD exceeds the
OVP trigger point.
7
HV
For startup, this pin is pulled HIGH to the line input or bulk capacitor via resistors.
