SY50281 Overview
Description
The SY50281 is a PWM controller with several features to enhance performance of Buck converters. It integrates a MOSFET with 500V breakdown voltage to decrease physical volume.
Key Features
- Integrated 500V MOSFET
- CC/CV control eliminates Aux-winding
- Quasi-Resonant (QR) mode to achieve low switching losses
- Fast Startup (<500ms)
- Low start up current: 15µA typical
- Maximum frequency limit: 45kHz
- Compact package: SOT23-5
