Improving time-to-market by simplifying the design process

Micrel Inc. unveiled a new family of power modules at APEC 2014 aimed at providing time-to-market gains. The MIC28304/MIC45205/MIC45208/MIC45212 family of power modules operate from 4.5V to 26.5V (70V for MIC28304) input and are capable of delivering currents of 3A, 6A, 10A and 14A, respectively.

The highly integrated power module solutions are designed to simplify the system power design process while offering exceptional performance. The modules feature a complete switching power supply solution in an ultra-compact, thermally enhanced, rugged, surface mount QFN 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. The MIC28304/MIC45205/ MIC45208/MIC45212 will be available in production and volume quantities starting in the second quarter of 2014 with pricing starting at $7.10/$4.85/$7.2/$8.88, respectively.

"This new generation of power modules allows our customers to improve their time-to-market by simplifying the design process. These modules eliminate the need to select key components and simplify the board layout to meet EMI specifications," explained Brian Hedayati, VP of marketing for high performance linear and power solutions at Micrel. "In addition, these modules reduce board space while still offering exceptional performance. These modules are among the highest input voltage rating and power density devices available in the market today."

The MIC28304/MIC45205/MIC45208/MIC45212 offer peak efficiency up to 93 per cent and are optimised for fast load transient responses by utilising Micrel's Hyperspeed ControlTM architecture. This minimises output capacitance to further reduce the overall solution size. In addition, these modules meet the industry's most demanding CISPR22, CLASS B, EMI standards, further reducing design complexity. The MIC28304 70V rating makes it suitable for applications such as automotive, industrial robotics, industrial automation, avionics and 48V telecom.

The modules protect against over-current, over-voltage and thermal faults. There is also an internal soft-start function that controls the inrush current.
