NCP1603 Product details

Description

Pin Symbol Function Description 1 Vaux 2 FB2 Auxiliary Supply PWM Feedback This pin connects to the VCC1 pin externally.It delivers a bias voltage from the VCC2 to the PFC section.The Vaux is disabled when either one of the following conditions occurs: (1) Vaux is initially off; (2) Fault (VFB2 > 3.0 V for more than 125 ms); (3) Standby (VFB2 < 0.75 V and then VFB2 is smaller than 1.25 V for more than 125 ms); (4) Overvoltage protection latch activated from CS2 pin; (5) Thermal shutdown
