Product Overview

The LTC3631IMS8E-5#PBF is a step-down DC/DC Converter with internal high side and synchronous power switches that draws only 12µA typical DC supply current at no load while maintaining output voltage regulation. The LTC3631 can supply up to 100mA load current and features a programmable peak current limit that provides a simple method for optimizing efficiency in lower current applications. It is a combination of Burst Mode® operation, integrated power switches, low quiescent current and programmable peak current limit provides high efficiency over a broad range of load currents. With its wide 4.5 to 45V input range and internal overvoltage monitor capable of protecting the part from 60V surges, it is a robust converter suited for regulating a wide variety of power sources. Additionally, the LTC3631 includes a precise run threshold and a soft-start feature to guarantee that power system start-up is well-controlled in any environment.
  • Overvoltage lockout provides protection up to 60V
