The LTM4646 is a complete dual 10A output switching mode DC/DC power supply. Included in the package are the switching controller, power FETs, inductors, and all supporting components. Operating from an input voltage range of 4.5V to 20V, the LTM4646 supports two outputs each with an output voltage range of 0.6V to 5.5V, set by external resistors. Its high efficiency design delivers up to 10A continuous current for each output. Only a few input and output capacitors are needed.
The device supports frequency synchronization, multiphase operation, high efficiency light load operation and output voltage tracking for supply rail sequencing and has an on-board temperature diode per channel 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 power module is offered in a small footprint 11.25mm × 15mm × 5.01mm BGA package. The LTM4646 is available with SnPb or RoHS compliant terminal finish.
