Description

NC

1, 8

-

NC — No connections

STBY

2IN

Remote On/Off Control — A voltage below 0.8 V shuts down the IC (not latched) and

brings the device into low power consumption mode. The input has an internal 600 k

Ω

pull-up resistor to the VDD pin and should be driven with an open-collector device.

IAC

3IN

fed into this pin. The current is measured with an A/D converter.

FB

4IN

PFC is fed into this pin. The current is measured with an A/D converter.

GND

5-

Ground — Current return for both the input signal portion of the IC and the gate driver.

GD

6OUT

Gate Driver Output — The totem pole stage is able to drive the power MOSFET with a

peak current of 0.5 A source and 1.0 A sink. The high-level voltage of this pin is

VDD

7IN

IC Supply Voltage — Supply voltage of both the input signal portion of the IC and the

gate driver.
