PSR Controller

PSR Controller

Product Description
The AP3708N/06/03 is a reliable high performance AC/DC power supply controller for battery charger and adapter applications. The device uses Pulse Frequency Modulation (PFM) technology to build discontinuous conduction mode (DCM) Flyback power supplies. The AP3708N/06/03 provides accurate constant voltage, constant current (CV/CC) regulation while removing the Opto-coupler and secondary control circuitry. It also eliminates the need of loop compensation circuitry while maintaining stability.

Product Highlight
- Primary side control for rectangular constant current
and constant voltage output
- Eliminates Opto-coupler and secondary CV/CC control
circuitry and control loop compensation circuilty
- Eliminates control loop compensation circuitry
- Output cable voltage drop compensation (for AP3708N)
- Built-in soft start
- Over voltage protection
- Short circuit protection

Application Area
- Adapter/Chargers for Cell/cordless phones, PDAs, MP3
and other Portable Apparatus
- Standby and Auxiliary Power Supplies
- LED Driver
