LTM4650IY-1A

LTM4650IY-1A is a dual 25A or single 50A output step-down µModule® (power module) regulator. Included in the package are the switching controller, power FETs, inductors, and all supporting components. External compensation allows for fast transient response to minimize output capacitance when powering FPGAs, ASICs, and processors. With synchronized multiphase parallel current sharing, six LTM4650-1 devices can deliver up to 300A. Applications include FPGA, ASIC, µProcessor core voltage regulation, information, communication systems.
