MPQ28164GD Description
The MPQ28164 is a high-efficiency, lowquiescent current, buck-boost converter that operates from an input voltage above, equal to, or below the output voltage. The MPQ28164 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 MPQ28164 uses current-mode control with a fixed PWM frequency for optimal...
