LTC3672B-2

Overview

The LTC®3672B-2 is a triple power supply composed of a 400mA synchronous buck regulator and two 150mA low-dropout linear regulators (LDOs). Constant-frequency 2.25MHz operation is maintained down to very light loads.

  • Triple Output Supply From a Single 2.9V to 5.5V Input
  • Buck DC/DC: Fixed 1.2V Output, Up to 400mA
  • LDO1: Fixed 2.8V Output, Up to 150mA
  • LDO2: Fixed 1.8V Output, Up to 150mA n ±2.5% Reference Accuracy
  • Constant-Frequency 2.25MHz Operation
  • Minimum External Component Count
  • Current Mode Operation for Excellent Line and Load Transient Response
  • Internal Soft-Start for Each Output
  • Single Enable Pin Turns On/Shuts Down All Three Outputs
  • Tiny 2mm × 2mm × 0.75mm DFN Package
