MxL7204 - Dual 4A Power Module


The MxL7204 power module is a complete dual 4A or single 8A output switch mode DC/DC power supply with an input voltage of 4.5V to 20V. It offers higher efficiency and improved thermal performance than 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 0.6V to 5.0V, set by a single external resistor. Its high efficiency design delivers up to 4A continuous current (5A 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 15mm × 15mm × 2.82mm LGA package.
