Product Overview

The LTC3631EMS8E#PBF is a high-voltage high-efficiency step-down DC-to-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. The LTC3631's 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, the LTC3631 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.
  • Internal high side and low side power switches
  • No compensation required
  • Low dropout operation - 100% duty cycle
  • Adjustable peak current limit
  • Internal and external soft-start
  • Precise RUN pin threshold with adjustable hysteresis
  • Only three external components required for fixed output versions
  • Overvoltage lockout provides protection up to 60V
  • 3.3V, 5V and adjustable Output version
