LTC7150SEY#PBF

2.5A/5A High Efficiency Step-Down Converter with Integrated MOSFETs

Product Description

Product Overview

The LTC7150SEY#PBF is a high efficiency synchronous step-down DC/DC converter that integrates high-side and low-side power MOSFETs to deliver up to 2.5A or 5A of continuous output current in a compact package. With current-mode control and optimized gate drive, the device provides excellent transient response, high efficiency over a wide load range, and stable operation over a wide input voltage range. This makes it ideal for distributed power systems, embedded controllers, industrial automation, and communication equipment power rails.
