DC444A, Demonstration Board using LTC1922, 12V, 20A Synchronous Phase Modulated Full-Bridge Controller
参考設計 著者: Analog Devices
DC444A, Demonstration Board provides an isolated 12V/20A from a 36 to 72VDC source. DC444 utilizes the LTC1922 controller to implement a zero voltage switched (ZVS), phase shift, full-bridge converter with synchronous rectification. Adaptive ZVS circuitry controls the turn-on of each primary MOSFET. The full bridge topology features excellent transformer utilization and low noise performance. The LTC1922 provides outputs for control of synchronous secondary MOSFETs resulting in high efficiency operation over line and load
