SAN JOSE, CA--(Marketwired - Mar 10, 2014) - Micrel, Inc. (
"Micrel's patented FleaFET™ Power MOSFET technology with inherent low gate charge structure enables our next generation of innovative point-of-load products. This technology allows Micrel to maximize the efficiency and frequency of operation while reducing the solution size and cost," stated Brian Hedayati, vice president of marketing for high performance linear and power solutions at Micrel. "The MIC23163/4 is designed for use with a very small 0.47 microhenry inductor that enables a total solution size of less than 1mm height. This makes the part ideal for applications where system designers want minimum thickness for their products including many new wearable electronic devices."
The MIC23163/4 has a very low quiescent current of 33 microamps and achieves as high as 85 percent efficiency at 1 microamp. At higher loads, the MIC23163/4 provides a constant switching frequency of around 4MHz while achieving peak efficiencies up to 93 percent. This helps increase system operating time for battery powered devices, an on-going concern for designers and consumers. Other features of these devices include an analog enable input, power good output, and an adjustable soft-start function. The MIC23164 also incorporates an internal switch to discharge the output capacitor when the device is shut down. These devices ensure safe startup into a pre-biased output and are specified to operate from -40degC to +125degC. They come in a 10-pin 2.0mm × 2.0mm Thin DFN package.
