AP3783R Description

Pin Assignments The AP3783R is a high frequency, high efficiency and high accuracy switching mode power supply controller to drive power MOSFET for 5V/2A battery charger/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 system operating frequency reduces linearly from heavy...
