Description

The AP3783 is a high performance AC/DC power supply controller for battery charger and adapter applications. The controller regulates the output voltage and current in the primary side by piece-wise Pulse Frequency Modulation (p-PFM) in discontinuous conduction mode (DCM).

The AP3783 provides accurate constant voltage (CV), constant current (CC) and outstanding dynamic performance without requiring an opto-coupler. It also eliminates the need of loop compensation circuitry while maintaining stability.

The AP3783 provides valley turn-on function, operating frequency Jitter function (about 5.5% frequency change every 256μs) from light to full load range and 3-segment drive current to improve the power supply EMI performance. The AP3783 also has built-in fixed cable voltage drop compensation (7% and 4% of nominal system output voltage to meet various cables with different length and gauge) and adjustable line voltage compensation.

The AP3783 is packaged in SOT26.
