Description

The LTM4634 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. VOUT1and VOUT2are adjustable from 0.8V to 5.5V, while VOUT3is 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 × 15mm × 5.01mm BGA package. The LTM4634 is available with SnPb (BGA) or RoHS compliant terminal finish.ApplicationsTelecom, Networking and Industrial EquipmentHigh Density Point of Load Voltage Regulation
