LTM4634EY#PBF

LTM4634 is a triple output step-down DC/DC µModule® regulator. It integrates three complete 5A/5A/4A high efficiency switching mode DC/DC converters into one small package. Switching controllers, power FETs, inductors, and most support components are included. VOUT1 and VOUT2 are adjustable from 0.8V to 5.5V, while VOUT3 is adjustable from 0.8V to 13.5V. Each output voltage is set by a single external resistor. High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. This device supports frequency synchronization, multiphase parallel operation, soft-start and output voltage tracking for supply rail sequencing. Fault protection features include overvoltage protection, overcurrent protection and temperature monitoring. It is widely used in application such as telecom, networking and industrial equipment, high density point of load voltage regulation etc.
