The ISL85415FRZ is a synchronous Buck Regulator with an input range of 3 to 36V. It provides an easy to use, high efficiency low BOM count solution for a variety of applications. The ISL85415 integrates both high-side and low-side NMOS FET"s 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 500kHz but may also be programmed using an external resistor from 300kHz to 2MHz. 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.
