Renesas has brought out a family of bidirectional four-switch synchronous buck-boost controllers. The ISL81601 and ISL81401 are  true bidirectional controllers that sense peak current at both ends and provide cycle-by-cycle current limit in both directions while in buck or boost mode. The controllers generate point-of-load (POL) and voltage rail conversions with peak efficiency up to ...
