The MP28164 is a high efficiency, low quiescent current buck/boost converter, which operates from input voltage above, equal, or below the output voltage.

Product Detail

The MP28164 is a high efficiency, low quiescent current buck/boost converter, which operates from input voltage above, equal, or below the output voltage. The device provides a compact solution for products powered by a one-cell Lithium-Ion or multi-cell alkaline battery, where the output voltage is within the battery voltage range. The MP28164 uses current mode control with a fixed PWM frequency for optimal stability and transient response. The fixed 2MHz switching frequency and integrated low RDS(ON) MOSFETs minimize the solution footprint while maintaining high efficiency. To ensure the longest battery life, the MP28164 has an optional pulse skipping mode that reduces the switching frequency under light-load conditions. For other low noise applications, where pulse skipping mode may cause interference, a high logic input on the MODE pin guarantees fixed-frequency PWM operation under all load conditions. The MP28164 operates with input voltage from 1.2V to 5.5V to provide adjustable output voltage (1.5V to 5V). With an input from 2.5V to 5.5V it can supply a maximum 2A current to the load at a 3.3V output voltage. The MP28164 is available in a small QFN-11(2mmx3mm) package.
