Switch mode DC-DC dual 13A power module
MaxLinear is demonstrating a new dual 13A or single 26A power module at the Applied Power Electronics Conference (APEC) in Anaheim, California, next week, its highest current module.

The MxL7213 is a complete switch mode DC-DC power supply with a wide 4.5V to 18V input voltage range for industrial, telecommunications, networking and infrastructure equipment.

The dual step-down power module integrates the control, drivers, bootstrap diodes, inductors and MOSFETs in a single package for point-of-load supplies. It supports two outputs each with a voltage range of 0.6V to 5.3V, set by a single external resistor, and supplies either two 13A outputs, a single 26A or up to 100A of multiphase current when paralleled with additional MxL7213 modules. It requires just a few input and output capacitors which simplifies design and shortens time-to-market and attention to thermal design, component selection and internal construction results in higher efficiency and extended operating range relative to devices with the same industry standard pinout.

Supply rail sequencing is supported as well as frequency synchronization, multiphase operation and output voltage tracking. Device temperature monitoring is accomplished with an onboard temperature diode. The peak current mode architecture provides very fast transient responses to line and load changes and doesn’t sacrifice stability.

“The MxL7213 is our highest output current power module solution to date,” said Joseph Tseng, Director of Marketing, Power Management. "It is the latest addition to our growing family of current mode, dual channel LGA/BGA power solutions targeted at networking and industrial equipment such as optical routers and test equipment. Our dual power modules offer system designers significant advantages over competing devices such as improved efficiency and better thermal performance.”

The MxL7213 is available in a 15mm x 15mm x 4.41mm LGA package and a 15mm x 15mm x 5.01mm BGA package with RoHS compliant terminal finish. Samples and evaluation boards are available.
