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 LiIon 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. The operating frequency can be divided by
two by raising the FREQ/2 pin to VDD. This allows the user to optimize
efficiency versus board space. It also allows the MIC2184 to be externally
synchronized to frequencies below its nominal 400KHz.
