MIC2183 controller equivalent, low voltage synchronous buck pwm controller.
an oscillator output, FreqOut, which can be used to implement a simple charge pump in low voltage applications. The output of the charge pump can be fed into the gate dri.
as well as in fixed 3.3V, 5V, or 12V systems.
Efficiencies over 90% are achievable over a wide range of load conditions.
Micrel’s MIC2183 is a high efficiency PWM synchronous buck control IC. With its wide input voltage range of 2.9V to 14V, the MIC2183 can be used to efficiently step voltages down in 1- or 2-cell Li Ion battery powered applications, as well as in fixe.
