VP3881 - High-Efficiency Boost/SEPIC/Flyback DC/DC Controller

Features

  • The VP3881 is a versatile controller designed for - Wide Input Voltage from 2.97V to 60V use in Boost, SEPIC and Flyback power converter - Reference Voltage with ± 3.0% Accuracy and topologies that needs an external low-side N- - Adjustable 100kHz~1MHz Clock Frequency MOSFET acting as primary switch. Besides cycle- - Wide Output Voltage up to 80V by-cycle current limiting, current mode control - 10μA Shutdown Current scheme also makes it wide bandwidth and good - 1A Peak Current Limit Usin.
