General Description

www.DataSheet4U.net Series STR-W6750 Off-Line Quasi-Resonant Switching Regulators INTRODUCTION TERMINAL FUNCTIONS 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.

The power supply of the control IC (VCC pin input) employs a circuit as shown in Figure 1.

At start-up, C3 is charged through a startup resistor R2.

Overview

g n i h tors c t i a Sw egul R Application Note 28103.30 PRODUCT.

Key Features

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).
