The ISL62870 IC is a Single-Phase Synchronous-Buck PWM voltage regulator featuring Intersil抯 Robust Ripple Regulator (R3) Technology™. The ISL62870 provides a low cost solution for compact high performance applications.The wide 3.3V to 25V input voltage range is ideal for systems that run on battery or AC adapter power sources. Resistor programmed output voltage setpoint and capacitor programmed soft-start delay allow for fast and easy implementation. Robust integrated MOSFET drivers and Schottky bootstrap diode reduce the implementation area and lower component cost.
