UCD74120 - Texas Instruments

UCD74120 Synchronous Buck Power-Stage

UCD74120 is a multi-chip module integrating a driver device and two NexFET power MOSFETs into a thermally enhanced compact, 5 mm × 7 mm, QFN package. A 25-A output current capability makes the device suitable for powering DSP and ASIC. The device is designed to complement digital or analog PWM controllers. The PWM input of the driver device is 3-state compat.
