LTM4601HVEV#PBF, Switching Voltage Regulators 12A 28VIN DC/DC Module (Power Module) Regulator with PLL, Output Tracking and Margining

LTM®4601HV is a complete 12A step-down switch mode DC/DC µModule regulator with PLL and with on-board switching controller, MOSFETs, inductor and all support components. Only bulk input and output capacitors are needed to complete the design. This 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. This 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. Typical applications are telecom and networking equipment, servers, industrial equipment, point of load regulation.
