EVQ28164-D-00A

EVQ28164-D-00A High Efficiency Single Inductor Buck-Boost DC-DC Converter Evaluation Board DESCRIPTION FEATURES The EVQ28164-D-00A Evaluation Board is designed to demonstrate the capabilities of MPS’ MPQ28164.              The MPQ28164 is a highly-efficient, low quiescent current Buck-Boost converter, which operates from input voltage above, below and equal to the output voltage. The device provides power solution for products powered by a one-cell Lithium-Ion or multi-cell alkaline battery applications where the output voltage is within battery voltage range. The MPQ28164 operates with input voltage from 1.2V to 5.5V to provide adjustable output voltage (1.5V to 5V), and is available in QFN103x3mm package.
