The NCP81075 is a high performance dual mosfet (high side and low side) gate-drive IC designed for high-voltage, high-speed, driving MOSFETs operating up to 180 V. The NCP81075 integrates a driver IC and a bootstrap diode and offers drive capability up to 4A. The high side and low side drivers are independently controlled with a matched typical propagation delay of 3.5ns. This driver is ideally suited for use in high voltage buck applications, isolated power supplies, 2 switch and active clamp forward converters. the device can also be used in solar optimizer and solar inverter applications. The part is offered in a SO8, 8 pin DFN, and 10 pin DFN package and fully specified from -40C to 140C.
