    LTM4634 Triple Output 5A/5A/4A Step-Down DC/DC µModule® Regulator FeaTures DescripTion
    The LTM®4634 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. Operating over an input voltage range of 4.75V to 28V, the LTM4634 provides three independent output voltages. 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. The 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. The power module is offered in a space saving, thermally enhanced 15mm Ч 15mm Ч 5.01mm BGA package. The LTM4634 is available with SnPb (BGA) or RoHS compliant terminal finish.
