The Renesas Synchronous Buck Regulator of 800 mA with an input range of 3V to 40V. It provides an easy-to-use, high efficiency low BOM count solution for a variety of applications. The ISL85418 integrates both high-side and low-side NMOS FETs and features a PFM mode for improved efficiency at light loads. This feature can be disabled if forced PWM mode is needed. The ISL85418 switches at a default frequency of 500kHz however it can also be programmed using an external resistor from 300kHz to 2MHz.

Wide input voltage range of 3V to 40V

Synchronous operation for high efficiency

Selectable PFM or forced PWM mode at light loads

Internal fixed frequency (500kHz) or adjustable switching frequency (300kHz to 2MHz)

Minimal external components required
