ANALOG DEVICES LTM4620IY DC/DC POL Converter, Adjustable, Buck, 4.5 to 16V in, 0.6 to 2.5V / 13A Out, BGA-144

LTM4620IY is a complete dual 13A output switching mode DC/DC power supply. Included in the package are the switching controller, power FETs, inductors, and all supporting components. Operating from an input voltage range of 4.5V to 16V, the LTM4620 supports two outputs each with an output voltage range of 0.6V to 2.5V, set by a single external resistor. Its high-efficiency design delivers up to 13A continuous current for each output. Only a few input and output capacitors are needed. This 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. Applications include telecom and networking equipment, storage and ATCA cards, industrial equipment.
