LP3792
LP3792 is Low Standby Power Off-Line PSR Driver manufactured by LANDP.
Description
The LP3792 is a high performance AC/DC power supply controller for battery charger and adapter applications. The device uses Pulse Frequency Modulation (PFM) method to build discontinuous conduction mode (DCM) flyback power supplies.
The LP3792 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 pensation circuitry while maintaining good stability.
The LP3792 can achieve excellent regulation and high average efficiency which is suitable for US Do E VI requirement, yet meets no-load consumption less than 75 m W.
The LP3792 provides many protections which include OVP ,OTP and output short protection.
The LP3792 is available in SOT23-6.
