20 Pin 1 16 Pin 1 Name HV Description This is the input of the high voltage startup regulator and connects directly to the bulk voltage.

A constant current source supplies current from this pin to the VCC capacitor, eliminating the need for an external startup resistor.

needed to implement a highly efficient and small form factor adapter. It integrates a critical conduction mode (CrM) power factor correction (PFC) controller and a half.
bridge controller with a built.
in 600 V driver. The half.
bridge stage operates at a fixed frequency. Regulation is achieved by adjusting the PFC stage output voltage. This device includes an enable input on the PFC feedback pin, open feedback loop protection and PFC overvoltage and undervoltage detectors.
