Micrel to Exhibit Products at APEC 2014

Micrel Inc. will be previewing analog technology solutions designed to make a difference at The Applied Power Electronics Conference and Exposition, APEC 2014.

The MIC28304/MIC45205/MIC45208/MIC45212 family of power modules operates from 4.5V to 26.5V (70V for MIC28304) input and are capable of delivering currents of 3A, 6A, 10A and 14A, respectively. These highly integrated power module solutions are designed to simplify the system power design process while offering exceptional performance.

These modules feature a complete switching power supply solution in an ultra-compact, thermally-enhanced, rugged surface mount package. The devices integrate a PWM controller, power MOSFETs, inductor, and associated discrete components to save board space and reduce component counts which results in higher system reliability.

The devices are ideally suited for RAID systems, network routers, blade servers, cellular base stations, medical test equipment, and test instrumentation. This new product will also be showcased in a live demonstration at the show.

The MIC33163/164 and MIC33263/64 family are high-efficiency, 4MHz, synchronous buck regulators with an integrated inductor capable of delivering current of 1A and 2A. In addition, the 100 percent duty cycle and HLL mode of operation delivers very high efficiency at light loads and ultra-fast transient response.

These modules provide the optimal trade-off between footprint and efficiency and are perfectly suited for space-constrained applications. They are also an excellent alternative for low dropout regulators for applications such as SSD and handheld devices.

The MIC33163/4 ultra-low profile of 1.1mm makes this part ideal for embedded point-of-load applications by providing a small, compact total solution with only a 22microF output capacitor and a few tiny external components.
