Renesas ISL85412

Beschreibung

The ISL85412 is a 150mA Synchronous buck regulator with an input range of 3.5V to 36V. It provides an easy to use, high efficiency low BOM count solution for a variety of applications. The ISL85412 integrates both high-side and low-side NMOSFET's and features a PFM mode for improved efficiency at light loads. This feature can be disabled if forced PWM mode isdesired. The part switches at a default frequency of 700kHz. By integrating both NMOS devices and providing internal configuration, 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. The part is available in a small Pb-free 3mmx3mm TDFNplastic package with an operation junction temperature range of -40°C to +125°C
