MaxLinear MxL7225 Dual Channel Power Modules

MaxLinear MxL7225 Dual Channel Power Modules are dual 25A or single 50A output step-down power modules with a 4.5V to 15V input voltage range. These modules support two outputs each with an output voltage range of 0.6V to 1.8V, set by a single external resistor. The MxL7225 power modules are capable of providing up to 300A when paralleled with additional MxL7225 modules. These power modules feature differential remote sense amplifier and peak current mode architecture for a fast transient response with 400kHz to 780kHz adjustable switching frequency. The MxL7225 dual-channel power modules offer overcurrent protection, output overvoltage protection, under-voltage lock-out, internal temperature monitor, and thermal shutdown protections. 

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 power modules are available in a thermally enhanced 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. Typical applications include telecom and networking equipment, industrial equipment, and test equipment.
