DATASHEET ISL8273M 80A Single Channel Digital PMBus Step-Down Power Module FN8704 Rev.4.00 Nov 9, 2017 The ISL8273M is a complete PMBus enabled DC/DC single channel step-down advance power supply capable of delivering up to 80A of current and optimized for high power density applications. For higher output current, up to four ISL8273Ms can be paralleled to supply up to 320A in a multiphase current sharing configuration. Operating over an input voltage range of 4.5V to 14V, the ISL8273M offers adjustable output voltages down to 0.6V and achieves up to 93% conversion efficiencies. A unique ChargeMode™ control architecture provides a single clock cycle response to an output load step and can support switching frequencies up to 1MHz.
