LTM4630 - Dual 18A or Single 36A DC/DC μModule (Power Module) Regulator
The LTM®4630 is a dual 18A or single 36A output switching mode step-down DC/DC μModule® (power module) regulator. Included in the package are the switching controllers, power FETs, inductors, and all supporting components. Operating from an input voltage range of 4.5V to 15V, the LTM4630 supports two outputs each with an output voltage range of 0.6V to 1.8V, each set by a single external resistor. Its high efficiency design delivers up to 18A continuous current for each output. Only a few input and output capacitors are needed. The LTM4630 is pin compatible with the LTM4620 and LTM4620A (dual 13A, single 26A) and the LTM4628 (dual 8A, single 16A).
The device supports frequency synchronization, multiphase operation, Burst Mode operation and output voltage tracking for supply rail sequencing and has an onboard temperature diode for device temperature monitoring. High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability.
Fault protection features include overvoltage and overcurrent protection. The LTM4630 is offered in 16mm × 16mm × 4.41mm LGA and 16mm × 16mm × 5.01mm BGA packages. The LTM4630 is ROHS compliant.
