MIC2183
Low Voltage Synchronous Buck PWM Control IC
General Description
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% are achievable over a wide range of load conditions with the MIC2183’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 e. |
