Monolithic Power Systems (MPS) MP023 Primary Side CC/CV Controller

Monolithic Power Systems (MPS) MP023 Primary Side CC/CV Controller features flyback topology and isolated output. This controller is designed with multiple protection features, including open loop (OCkP), overload (OLP), undervoltage lockout (UVLO), overtemperature (OTP) and overvoltage (OVP). The voltage supply range is 10V to 25V, with a variable switching frequency and a maximum secondary duty cycle. MPS MP023 Primary Side CC/CV Controller offers 20mW no-load power consumption and offers accurate, constant voltage, and constant current regulation. The controller does not require an optocoupler or secondary feedback circuit. The device comes in a SOIC8-7A package.
