Beschreibung
- AP3984EV1, Evaluation Board for the AP3984 stands out as an extremely low stand by power (<10mW) Primary Side Regulation (PSR) switcher for power supplies based on optimal cost-effectiveness, efficiency, Constant Voltage (CV) & Constant Current (CC) accuracy, and versatile protection functions. The AP3984, with built-in Bipolar Junction Transistor (BJT), regulates the output voltage and current in the primary side by piece-wise Pulse Frequency Modulation (p-PFM) and primary current peak Amplitude Modulation (AM) in discontinuous conduction mode (DCM). The system operating frequency reduces linearly from heavy load to light load in each interval of the p-PFM, and operating frequency is fixed at medium load by varying primary current peak amplitude
