AR2003FV中文资料Synchronous Controller数据手册Diodes规格书

描述 Description

The AR2003 is Active/Synchronous Rectification Controller, providing output voltage from 4.5V to 20V. Using internal drain-to-source voltage sensing, the AR2003 is ideal for Flyback, LLC-resonant and other power supply architectures. By using SFB pin, output voltage can be changed dynamically by changing the Output Voltage Control pin’s level.
