The LTM4628 is a complete dual 8A output switching mode DC/DC power supply and can be easily configured to provide a single 2-phase 16A output. Included in the package are the switching controller, power FETs, inductor, and all supporting components. Operating from an input voltage range of 4.5V to 26.5V, the LTM4628 supports two outputs each with an output voltage range of 0.6V to 5.5V, set by a single external resistor. Its high efficiency design delivers 8A continuous current for each output. Only a few input and output capacitors are needed.

The device supports frequency synchronization, multiphase operation, Burst Mode operation and output voltage tracking for supply rail sequencing. It has an on-board 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 power module is offered in space saving and thermally enhanced 15mm × 15mm × 4.32mm LGA and 15mm × 15mm × 4.92mm BGA packages. The LTM4628 is available with SnPb (BGA) or RoHS compliant terminal finish.

Product Detail

Demonstration circuit DC1663A features the LTM4628EV, the high efficiency, high density, dual 8A output, switch mode step-down power module. The input voltage is from 4.5V to 26.5V. The output voltage is programmable from 0.6V to 5.5V. Output current derating is necessary for certain VIN, VOUT, and thermal conditions. The board operates in continuous conduction mode in heavy load conditions. For high efficiency at low load currents, the MODE jumper (JP1) selects pulse-skipping mode for noise sensitive applications or Burst Mode® operation in less noise sensitive applications. The DC1663A sets the LTM4628EV default switching frequency to 400kHz; however the frequency is resistor programmable from 250kHz up to 780kHz.
