AP8007
AC-DC PWM CONTROLLER PRIMARY SWITCHING
REGULATORS
DESCRIPTION
The AP8007 is a high performance AC-DC off‐line controller for low power battery charger and adapter applications with Universal‐input.
It uses Pulse Frequency and Width Modulation (PFWM) method to build discontinuous conduction mode (DCM) flyback power supplies.
The AP8007 utilizes primary‐side sensing and regulation technology to provide accurate constant voltage, constant current (CV/CC) regulation without requiring an opto‐coupler and secondary control circuitry.
It also eliminates the need of external loop compensation circuitry while maintaining stability.
The AP8007 achieves ex...
