MP020A-5

Offline, Primary-Side Regulator with CC/CV Control and a 700V MOSFET

Datasheet

概要

The MP020A-5 is an offline, primary-side regulator that provides accurate constant voltage and constant current regulation without an optocoupler or a secondary feedback circuit. The MP020A-5 has an integrated 700V MOSFET.

The MP020A-5's variable off-time control allows a flyback converter to operate in discontinuous conduction mode (DCM). The MP020A-5 also features protection functions such as VCC under-voltage lockout (UVLO), over-current protection (OCP), over-temperature protection (OTP), open-circuit protection (OCkP), and over-voltage protection (OVP). Its internal high-voltage start-up current source and power-saving technologies limit the no-load power consumption to less than 30mW.

The MP020A-5's variable switching frequency technology provides natural spectrum shaping to smooth the EMI signature, making it suitable for offline, low-power battery chargers and adapters.

The MP020A-5 is available in a SOIC8-7A package.
