MaxLinear MXL7225-1-ABA-T

The MxL7225 is a dual channel, 25A step-down power module. It includes a wide 4.5V to 15V input voltage range and supports two outputs each with an output voltage range of 0.6V to 1.8V, set by a single external resistor. The MxL7225 requires only a few input and output capacitors, which simplifies design and shortens time-to-market. The module supplies either two 25A outputs, a single 50A output or up to 300A when paralleled with additional MxL7225 modules. A unique package design where inductors are mounted externally provides improved thermal performance and lower cost relative to devices with the same industry standard pinout.

• The complete switch mode DC/DC power supply integrates the control, drivers, bootstrap diodes, bootstrap capacitors, inductors, MOSFETs and HF bypass capacitors in a single package for point-of-load conversions.
• The MxL7225 includes a temperature diode that enables device temperature monitoring.
• It also has an adjustable switching frequency and utilizes a peak current mode architecture which allows fast line and load transient response.
• A host of protection features, including overcurrent, overtemperature, output overvoltage and UVLO, help this module achieve safe operation under abnormal operating conditions.
• The MxL7225 is available in a space saving 16mm x 16mm x 5.01mm RoHS compliant BGA package.
• The MxL7225-1 is identical to the MxL7225 except that there are no internal feedback loop compensation components.
• When more flexibility is desired in dealing with loop characteristics, the MxL7225-1 allows the system designer to use an external compensation network entirely different from that embedded in the MxL7225.
