Description

The MP020-5 is an offline, primary-side regulator that provides accurate constant voltage and constant current regulation without an opto-coupler or a secondary feedback circuit. It has an integrated 700V MOSFET. The MP020-5's variable off-time control allows a flyback converter to operate in discontinuous conduction mode. The MP020-5 also features protection functions such as VCC under-voltage lockout, over-current protection, over-temperature protection, open-loop protection and over-voltage protection. Its internal high-voltage start-up current source and power-saving technologies limit the no-load power consumption to less than 30mW. The MP020-5'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 MP020-5 is available in SOIC8-7A.
