MP020A-5GS-Z

AC DC Converters, Offline Switchers Overview

The MP020A-5GS-Z is an offline primary-side regulator featuring integrated constant voltage and constant current control, eliminating the need for optocouplers or secondary feedback circuits. It incorporates a high-voltage 700V MOSFET to minimize external component count. The device utilizes variable off-time peak current mode control, supporting discontinuous conduction mode (DCM) operation in flyback converters. Key electrical characteristics include a 550µA high-voltage startup current source and programmable line compensation. It achieves ultra-low no-load power consumption of less than 30mW through energy-saving techniques. The IC includes comprehensive protection mechanisms such as UVLO, OCP, OTP, open-loop protection, and OVP.
