LT LTM4623EY#PBF

Неизолированный модуль PoL4V20V0.6 ~ 5.5V3A

Overview

DESCRIPTION  The LTMe4623 is a complete 3A step-down switching mode uModule(micromodule) regulator in a tiny ultrathin 6.25mm×6.25mm×1.82mm LGAand6.25mm×6.25mm×2.42mm BGA packages. Included in the package are theswitching controller, power FETs, inductor and support components. Operating over an input voltage range of 4V to 20V or 2.375V to 20V with an external bias supply, the LTM4623EY#PBF supports an output voltage range of 0.6V to 5.5V, set by a single external resistor. Its high efficiency design delivers 3A continuous outputcurrent. Only ceramic input and output capacitors are needed. The LTM4623EY#PBF supports selectable discontinuous mode operation and output voltage tracking for supply rail sequencing. Its high switching frequency and current mode control enable a very fast transient response to line and load changes without sacrificing stability. Fault protection features include overvoltage, overcurrent and overtemperature protection.  The LTM4623EY#PBF is available with SnPb(BGA) or RoHS compliant terminal finish.
