Overview
FM25XX is a low-power Primary-Side Regulation (PSR) switching power supply IC with an integrated high-power MOSFET, designed for isolated high-efficiency low-power portable device charger applications. It employs a unique PSR control technique with CC/CV functionality, along with a proprietary PFM+PWM scheme to reduce the IC's own power consumption under light load for high-efficiency operation. Output cable drop compensation is incorporated to ensure sufficient output power at high current. Additional features include over-temperature protection, VCC under-voltage protection, VCC over-voltage protection, and output short-circuit protection. The compact DIP/SOP package facilitates system design and PCB layout.
Applications
- Chargers and adapters for portable devices such as mobile phones
- LED driver power supplies
- Auxiliary power supplies
Key features
- Integrated high-power MOSFET
- High-precision constant voltage and constant current control
- PFM+PWM mode
- Standby power consumption < 75mW
- No audio noise
- Output short-circuit protection
- VCC overvoltage and clamp protection
- VCC undervoltage protection
- Over-temperature protection
- Primary-side feedback with minimal external components
