LP3783 Low Standby Power Off-Line PSR Driver Description The LP3783 is a high performance AC/DC power supply controller for battery charger and adapter applications which integrated 750V high voltage BJT. The device uses Pulse Frequency Modulation (PFM) method to build discontinuous conduction mode (DCM) flyback power supplies. The LP3783 provides accurate constant voltage, constant current (CV/CC) regulation without requiring opto-coupler and the secondary control circuitry. It also eliminates the need of loop compensation circuitry while maintaining good stability. The LP3783 can achieve excellent regulation and high average efficiency which is suitable for US DoE VI requirement, yet meets no-load consumption less than 75 mW.
