The ON NCP81381 integrated chip combines a MOSFET driver and high-side and low-side MOSFETs in one package. It is optimized for high-current DC-DC buck power conversion and reduces package parasitics and required board space compared with a discrete-component solution.

It supports an average current of up to 25 A, a peak current of up to 60 A, and a switching frequency of up to 2 MHz. It includes an internal bootstrap diode, undervoltage protection, a thermal warning output, and thermal shutdown.
