Description of Pin Functions
OUT Pin:
The power MOS FET gate-drive signal is output from this pin, and takes the form of a rectangular waveform with an
amplitude of VCC-GND.
GND Pin:
The ground terminal.
DELAY Pin:
This pin has two functions; (1) setting the PFC function hold time for cases of momentary outage and (2) IC shutdown.
Current that flows through the DELAY pin is in inverse proportion to the RT pin resistance. Source current is 4.7/RT
[A] and sink current is 42.3/RT [A]. Normal operation is in the state that sink current flows.
