SY5011FAC数据手册Silergy中文资料规格书

描述 Description

SY5011 is a single stage Flyback and PFC controller with several features to enhance performance of Flyback converters. Both current and voltage regulation are achieved by primary side control technology for low cost application. To achieve higher efficiency and better EMI performance, SY5011 drives Flyback converters in the Quasi-Resonant mode.

特性 Features

• Primary side CV/CC control eliminates the optocoupler.\r
• Valley turn-on of the primary MOSFET to achieve low switching losses\r
• Internal high current MOSFET driver: 1A sourcing and 2A sinking\r
• Power factor >0.90 with single-stage conversion\r
• Low start up current: 15µA typical\r
• Maximum switching frequency limitation 200kHz\r
• Compact package: SO8

应用 Application

• AC/DC adapters\r
• Battery Chargers
