Description:

Low voltage buck pwm controller.

MIC2184, Low Voltage Buck PWM Controller

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 achievab

MIC2184 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, allowing enhanced gate drive, hence higher efficiencies, despite low input voltages. MIC2184
