ISL85415 Synchronous Buck Regulator

ISL85415 Synchronous Buck Regulator

The Intersil ISL85415 is a 500 mA synchronous buck regulator with an input range of 3 V to 36 V. It provides an easy-to-use, high-efficiency low BOM-count solution for a variety of applications.

The ISL85415 integrates both high- and low-side NMOSFETs and features a PFM mode for improved efficiency at light loads. This feature can be disabled if forced PWM mode is desired. The part switches at a default frequency of 500 kHz, but may also be programmed using an external resistor from 300 kHz to 2 MHz. The ISL85415 has the ability to utilize internal or external compensation. By integrating both NMOS devices and providing internal configuration options, minimal external components are required, reducing BOM count and complexity of design.

With the wide VIN range and reduced BOM, the part provides an easy-to-implement design solution for a variety of applications while giving superior performance. It will provide a very robust design for high-voltage industrial applications, as well as an efficient solution for battery powered applications.
