MIC2183, Low Voltage Synchronous Buck PWM Controller
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 fixed 3.3V, 5V, or 12V systems.
Efficiencies over 90%
MIC2183 Features
* 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 drive power circuitry via the VINP pin. This feature allows enhanced gate drive, hence higher efficiencies at low input voltages. MIC
