The MP024-10 is a low-cost, offline, primary-side, flyback regulator with a simple, external circuit. It provides accurate constant voltage (CV) and constant current (CC) regulation without an optocoupler or secondary feedback circuit and has an integrated 700V MOSFET and high-voltage start-up current source. 

The MP024-10 operates in discontinuous conduction mode (DCM) using variable off-time control. Its power-saving technologies limit the no-load power consumption to less than 30mW.

Full protection features include VCC under-voltage lockout (VCC UVLO), overload protection (OLP), over-temperature protection (OTP), open-loop protection (OCkP), sensing-short protection (SSP), and over-voltage protection (OVP). 
The variable switching frequency method provides natural spectrum shaping to smooth the EMI signature, making the MP024-10 suitable for offline, low-power battery chargers and adapters.
