EVM3684-RU-00A Datasheet, PDF (1/7 Pages) MPS Industries, Inc. – 18V 15A Step-Down Power Module Evaluation Board

The Future of Analog IC Technology
DESCRIPTION
The EVM3684-RU-00A is used for
demonstrating the performance of MPS’
MPM3684, a 15A step-down power module
with built-in power MOSFETs and power
inductor.
High power efficiency over a wide load range is
achieved by scaling down the switching
frequency at light load to reduce the switching
related loss by constant on time control. Over-
Current-Protection, Over-Voltage Protection,
Under-Voltage Protection, and thermal
shutdown provide reliable operation.
MPM3684 is available in QFN 12x15x4mm
package.
