Pin Description
This pin is a direct connection to the V CC pin (Pin 6) via a low impedance switch. In
standby and during the startup sequence, the switch is open and the PFC V CC is
shut down. As soon as the aux. winding is stabilized, Pin 1 connects to the V CC pin
and provides bias to the PFC controller. It goes down in standby and fault conditions.
An optocoupler collector pulls this pin low to regulate. When the current setpoint
reaches 25% of the maximum peak, the controller skips cycles.
This pin incorporates three different functions: the current sense function, an internal
ramp compensation signal and a 3.0 V latch ? off level which latches the output off
until V CC is recycled.
?
With a drive capability of +500 mA / ? 800 mA, the NCP1230 can drive large Qg
MOSFETs.
The controller accepts voltages up to 18 V and features a UVLO turn ? off threshold of
7.7 V typical.
?
This pin connects to the bulk voltage and offers a lossless startup sequence. The
charging current is high enough to support the bias needs of a PWM controller
through Pin 1.
