LTM4646IY#PBF

LTM4646 is a complete dual output switching mode DC/DC power supply. This device supports frequency synchronization, multiphase operation, high efficiency light load operation and output voltage tracking for supply rail sequencing and has an on-board temperature diode per channel for device temperature monitoring. High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. Fault protection features include overvoltage and overcurrent protection. It is widely used in application such as point-of-load power supplies, telecom and networking equipment, industrial equipment, medical equipment etc.
