Bidirectional synchronous buck-boost controllers serve industrial battery powered apps

RENESAS ELECTRONICS ISL81601 and ISL81401 bidirectional four-switch synchronous buck-boost controllers sense peak current at both ends and provide cycle-by-cycle current limit in both directions while in buck or boost mode. Devices generate point-of-load (POL) and voltage rail conversions with peak efficiency up to 99%. Devices have a wide input range of 4.5V to 60V and produce a 0.8V to 60V output to support most industrial batteries: 12V, 24V, 36V and 48V.
