Description
The MP023 is an offline, primary-side controller that provides accurate, constant voltage and constant current regulation without the need of an optocoupler or secondary feedback circuit.
Features
- include VCC undervoltage lockout (UVLO), overload protection (OLP), over-temperature protection (OTP), open loop protection (OCkP), and over-voltage protection (OVP). The MP023's variable switching frequency method provides a natural spectrum for shaping a smooth EMI signature, which is suitable for offline, low-power battery chargers and adapters. The MP023 requires a minimal number of readily available, standard, external components and is available in a SOIC8-7A package.
