VCC (Pin 4) Start-up circuit The start-up circuit detects the VCC pin voltage (pin 4), and makes the control IC start and stop operation.

Blocking (or intermittent) oscillation operation by reducing output voltage in the standby mode. In addition to the standard quasi-resonant operation, a bottom-skip function is available for increased efficiency from light to medium load. Soft-start operation at start-up. Reduced switching noise (compared to conventional PWM hard-switching solution) with a step-drive function. Built-in avalanche-energy-guaranteed power MOSFET (to simplify surge-absorption circuit; no VDSS derating is required).
