Exar's MxL7204 power module is a complete dual 4 A or single 8 A output switch mode DC/DC power supply with an input voltage of 4.5 V to 20 V. It offers higher efficiency and improved thermal performance versus the competition while matching pinout and functionality. Power modules integrate the switching controller, power FETs, inductors, and all supporting components. The MxL7204 supports two outputs each with an output voltage range of 0.6 V to 5.0 V, set by a single external resistor. Its high-efficiency design delivers up to 4 A continuous current (5 A peak) for each output. Only a few input and output capacitors are needed.

The device supports frequency synchronization, multiphase operation, and output voltage tracking for supply rail sequencing. 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, overcurrent, and over temperature protection. The power module is offered in a space saving and thermally enhanced 15 mm × 15 mm × 2.82 mm LGA package.
