Description

The LTM®4620 is a complete dual 13A 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 16V, the LTM4620 supports two outputs

each with an output voltage range of 0.6V to 2.5V, set by a

single external resistor. Its high efficiency design delivers

up to 13A continuous current for each output. Only a few

input and output capacitors are needed.

The device supports frequency synchronization, multi-

phase 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 overcur-

rent protection. The power module is offered in a proprietary

spacewww.DataSheet.net/ saving and thermally enhanced 15mm × 15mm ×

4.41mm LGA package with integrated top-side heat sink.

The LTM4620 is RoHS compliant with a PB-free finish.
