The low profile (2.8mm) and light weight (1.73g) package easily mounts on the unused space on the back side of PC boards for high density point of load regulation. The Module 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 onboard remote sense amplifier can be used to accurately regulate an output voltage independent of load current. The onboard remote sense amplifier is not available in the LTM4603-1. The LTM4603/LTM4603-1 are pin compatible with the 12A LTM4601/LTM4601-1. , LT, LTC, LTM and PolyPhase are registered trademarks of Linear Technology Corporation.
