The LTM®4646 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
onboard 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.
