General Description

Micrel’s MIC2184 is a high efficiency PWM buck control IC.

With its wide input voltage range of 2.9V to 14V, the MIC2184 can be used to efficiently step voltages down in 1- or 2-cell Li Ion battery powered applications, as well as in fixed 3.3V, 5V, or 12V systems.

Efficiencies over 90% are achievable over a wide range of load conditions with the MIC2184’s PWM control scheme.
