LTM4601IY#PBF

LTM®4601 is a complete step-down switch mode DC/DC µModule regulator with PLL with on-board switching controller, MOSFETs, inductor and all support components. Only bulk input and output capacitors are needed to complete the design. The low profile and light weight package easily mounts in unused space on the back side of PC boards for high density point of load regulation. The µModule regulator can be synchronized with an external clock for reducing undesirable frequency harmonics and allows PolyPhase® operation for high load currents. A high switching frequency and adaptive on-time current mode architecture deliver a very fast transient response to line and load changes without sacrificing stability. An on-board differential remote sense amplifier can be used to accurately regulate an output voltage independent of load current. Applications are telecom and networking equipment, servers, industrial equipment, point of load regulation.
