用于谐振开关电容变换器优化运行的数字零电流开关锁定控制器IC

This article introduces a lock-in integrated controller for resonant switched-capacitor converter (SCC). The controller identifies the resonant period of each subcircuit on-the-fly and locks-in to the correct switching time to fully utilize the charge transfer rate for each flying capacitor. The various modules of the controller are detailed, including the autotuner and sequencer, which accommodat...
