MP28164 Overview
The MP28164 is a high-efficiency, lowquiescent current, buck-boost converter that operates from an input voltage above, equal to, or below the output voltage. The device provides a pact solution for products powered by one-cell Lithium-Ion or multi-cell alkaline batteries where the output voltage is within the battery voltage range. The MP28164 uses current-mode control with fixed PWM frequency for optimal stability...
