The wide 3.3V to 25V input voltage range is ideal for systems that run on battery or AC-adapter power sources.

ISL62873 Features

* Robust integrated MOSFET drivers and Schottky bootstrap diode reduce the implementation area and lower component cost. Intersil’s R3 Technology™ combines the best features of both fixed-frequency and hysteretic PWM control. The PWM frequency is 300kHz during static operation, becoming variable duri
