Description

General part information

ISL854102 Series

The ISL854102 is a 1. 2A synchronous buck regulator 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 ISL854102 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 a forced PWM mode is needed. The ISL854102 switches at a default frequency of 500kHz; however, it can also be programmed using an external resistor from 300kHz to 2MHz. The ISL854102 has the ability to use internal or external compensation. By integrating both NMOS devices and providing internal configuration options, minimal external components are required, which reduces the BOM count and design complexity. With a wide VINrange and reduced BOM, the ISL854102 provides an easy to implement design solution for a variety of applications while giving superior performance. The ISL854102 provides a very robust design for high-voltage industrial applications and an efficient solution for battery powered applications. The ISL854102 is available in a small Pb-free 4mmx3mm DFN plastic package with a full-range industrial temperature of -40°C to +125°C.
