Micrel Inc., (Nasdaq: MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, launched the MIC2225, an ultra-small dual channel power management IC that provides two high-performance outputs. The integration of a 2MHz synchronous buck regulator with an independent 300mA LDO offers portable electronics designers maximum flexibility for space constrained applications such as smart phones, GPS and digital still cameras. The MIC2225 is an ideal solution for applications where an additional set of voltages is needed to support an applications processor or co-processor. The MIC2225 is currently available in volume, with pricing at $1.30, for 1K quantities.
“The MIC2225 addresses three major concerns in today’s portable electronic market: performance, size, and cost,” said Ralf Muenster Micrel’s marketing director for power products. “With high efficiency and small board area, circuit designers will find the MIC2225 an optimally balanced solution for converged portable devices that require more than one processor.”
The combination of the 600mA DC-to-DC plus 300mA linear regulator permits the use of small value inductors and capacitors that reduce board space, support continuous load currents up to 600mA, and achieve more than 90 percent efficiency. The MIC2225 employs a micron Cap design which allows stable operation with very small ceramic output capacitors and a small inductor. This reduces required board space and external component cost. Fixed output voltages options are available down to 1V on the DC-to-DC converter and 0.8V on the LDO. The unique PWM architecture also offers fast transient response, high efficiency and low output ripple. The package is a very small leadless 10-pin 2mm x 2mm thin MLF(R) with a junction range temperature from -40-degC to +125 degC.
