Product Overview

The LTM4630EY#PBF is a Micromodule® step-down DC-to-DC Regulator with switching controllers, power FETs, inductors and all supporting components. Operating from an input voltage range of 4.5 to 15V, the LTM4630 supports two outputs each with an output voltage range of 0.6 to 1.8V, each set by a single external resistor. Its high efficiency design delivers up to 18A continuous current for each output. Only a few input and output capacitors are needed. The LTM4630 is pin compatible with the LTM4620 and LTM4620A (dual 13A, single 26A) and the LTM4628 (dual 8A, single 16A). The device supports frequency synchronization, multiphase operation, Burst Mode® operation and output voltage tracking for supply rail sequencing and has an onboard temperature diode for device temperature monitoring. High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability.
  • Differential remote sense amplifier
  • Current-mode control/fast transient response
  • Adjustable switching frequency
  • Overcurrent foldback protection
  • Frequency synchronization
  • Internal temperature monitor
  • Soft-start/voltage tracking
  • Output overvoltage protection
  • Multiphase parallel current sharing with multiple LTM4630's up to 144A
  • ±1.5% Maximum total DC output error over line, load and temperature
