The is a step-down DC/DC µModule Regulator combines three complete 10A switching mode DC/DC converters into one small package. It includes the switching controllers, power FETs, inductors and most support components. The LTM4633 regulator operates from 4.7 to 16V input rails or 2.375 to 16V with an external 5V bias. The VOUT1 and VOUT2 output range is 0.8 to 1.8V, while the VOUT3 output range is 0.8 to 5.5V. Each output is set by one external resistor. High switching frequency and 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 VOUT1 and VOUT2, soft-start and output voltage tracking for supply rail sequencing. Fault protection features include overvoltage protection, overcurrent protection and temperature monitoring.
