SY50103中文资料内置MOS管 高效率5V/1.8A AC-DC控制器数据手册Silergy规格书

描述 Description

SY50103 is a PWM controller with several features to enhance performance of Flyback converters. It integrates a 600V MOSFET to decrease physical volume. Both current and voltage regulation are achieved by primary side control technology for low cost application. To achieve higher efficiency and better EMI performance, SY50103 drives Flyback converters in the Quasi-Resonant mode.

特性 Features

• Integrated 600V MOSFET
• Primary side CV/CC control eliminates the optocoupler

• Low start up current: 15µA typical
• Maximum switching frequency limitation 120kHz
• Compact package: SO8

应用 Application

• AC/DC adapters
• Battery Chargers
