Overview

www.fairchildsemi.com AN-6073 FAN6751 — Highly Integrated Green-Mode PWM Controller Introduction This application note describes a detailed design strategy for a high-efficiency, compact flyback converter.

Design considerations and mathematical equations are presented as well as guidelines for a printed circuit board layout.

Key Features

to enhance the performance for LCDM/TV, NB, and adapters. The green-mode function includes off-time modulation and burst mode to reduce the PWM frequency at light-load and in no-load conditions. To avoid acoustic noise problems, the minimum PWM frequency is set above 18KHz. This greenmode function enables the power supply to meet international power conservation requirements. With the internal high-voltage startup circuitry, the power loss due to bleeding resistors is also eliminated. Built-in s.
