MxL7218

Dual 18A or Single 36A Power Module
Data Sheet

Description

The MxL7218 is a dual channel, 18A 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 MxL7218 requires just a few input and output capacitors, which simplifies design and shortens time-to-market. The module supplies either two 18A outputs, a single 36A output or up to 216A when paralleled with additional MxL7218 modules. A unique package design where inductors are mounted externally and careful component selection result in higher efficiency and extended operating range 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 MxL7218 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 MxL7218 is available in a space saving 16mm x 16mm x 5.01mm RoHS compliant BGA package.
