AC DC Converters, Offline Switchers datasheet and documents for MP020A-5GS
AC DC Converters, Offline Switchers Overview
The MP020A-5GS is an offline primary-side regulator featuring a built-in 700V MOSFET. It provides precise constant voltage and constant current control without requiring optocouplers or secondary feedback circuits. The device utilizes variable turn-off time peak current mode control to support discontinuous conduction mode operation in flyback converters. It includes a 550µA high-voltage startup current source and achieves no-load power consumption below 30mW through energy-saving techniques.
AC DC Converters, Offline Switchers Feature Summary
- Primary-side regulation eliminates the need for optocouplers or secondary feedback loops
- Integrated 700V MOSFET minimizes external component count
- Variable switching frequency with natural dithering reduces electromagnetic interference
