Description

General part information

LTM4691 Series

The LTM4691 is a complete dual 2A output switching mode DC/DC power supply in a tiny 3mm × 4mm × 1.18mm LGA package and a 3mm × 4mm × 1.48mm BGA package. Included in the package are the switching controller, power FETs, inductors and all supporting components. Operating over an input voltage range of 2.25V to 3.6V, the LTM4691 supports two outputs with programmable output voltage range from 0.5V to 2.5V set by external resistors. Its high efficiency design delivers up to 2A continuous current on each output. Only bulk input and output capacitors are needed.The LTM4691 operates in forced continuous mode for low noise pulse-skipping mode or Burst Mode operation for high efficiency at lights loads. The typical buck switching frequency is 2MHz and can be synchronized from 1MHz to 3MHz. Its high switching frequency and a current mode architecture enables a very fast transient response to line and load changes without sacrificing stability.Other features include precision run thresholds, a PGOOD signal, output overvoltage protection, thermal shutdown and output short-circuit protection. The LTM4691 is Pb-free and RoHS compliant.ApplicationsTelecom, Networking and Industrial EquipmentPoint-of-Load RegulationFPGA, ASIC Core Supplies
