Description

The LTM4633 μModule®(power module) regulator combines three complete 10A switching mode DC/DC converters into one small package. Included in the package are the switching controllers, power FETs, inductors, and most support components. The LTM4633’s three regulators operate from 4.7V to 16V input rail(s) or 2.375V to 16V with an external 5V bias. The VOUT1and VOUT2output range is 0.8V to 1.8V, while the VOUT3output range is 0.8V to 5.5V. Each output is set by one external resistor.High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. The device supports frequency synchronization, multiphase parallel operation of VOUT1and VOUT2, soft-start and output voltage tracking for supply rail sequencing.Fault protection features include overvoltage protection, overcurrent protection and temperature monitoring. The power module is offered in a space saving, thermally enhanced 15mm × 15mm × 5.01mm BGA package. The LTM4633 is RoHS compliant with Pb-free finish.ApplicationsTelecom, Networking and Industrial EquipmentHigh Density Point of Load Regulation
