This pin is a direct connection to the V
standby and during the startup sequence, the switch is open and the PFC V
shut down. As soon as the aux. winding is stabilized, Pin 1 connects to the V
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
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.
