MIC2145BML-TR 产品详情

The MIC2145BML-TR is a small size boost switching regulator that can provide over 2.5W of output power. The input voltage range is between 2.4V to 16V, making the device suitable for one-cell Li-Ion and 3- to 4-cell alkaline/NiCad/NiMH applications. The output voltage of the MIC2145BML-TR can be adjusted up to 16V.

The MIC2145BML-TR is well suited for portable, space-sensitive applications. Its typical 450kHz operation allows small surface mount external components to be used. The MIC2145BML-TR has a low quiescent current of 200µA, and a typical shutdown current of 0.5µA. The MIC2145BML-TR is capable of high efficiencies in a small board area.

The MIC2145BML-TR features a low-on resistance internal switch that allows it to provide over 2.5W of output power. The peak switch current can be programmed through an external resistor. This allows the user to set the peak switch current at the level where maximum efficiency occurs. It also allows the user to further optimize for efficiency and inductor size by setting the peak current below the level of inductor saturation.

The MIC2145BML-TR is available in an MSOP-8 package with an ambient operating temperature range from -40°C to +85°C.
