LTM4648EY#PBF

LINEAR TECHNOLOGY  LTM4648EY#PBF  直流-直流开关降压稳压器, 可调, 2.375V-5.5V输入, 600mV-5V/10A输出, 450 kHz, BGA-68

The is a Micromodule® step-down DC-to-DC Regulator with switching controller, power FETs, inductor and all support components. Operating over an input voltage range of 2.375 to 5.5V, the LTM4648 supports an output voltage range of 0.6 to 5V, set by a single external resistor. This high efficiency design delivers up to 10A continuous current. Only bulk input and output capacitors are needed. 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, programmable multiphase operation and output voltage tracking for supply rail sequencing. Fault protection features include overvoltage protection, overcurrent protection and thermal shutdown.
