SAN JOSE, Calif., Dec. 14 /PRNewswire-AsiaNet/ –

Micrel Inc. (Nasdaq: MCRL), an industry leader in analog, high bandwidth
communications and Ethernet IC solutions, today launched the MIC4722, a 3 mm x
3 mm MLF(R) 2.7MHz 3A PWM buck regulator and the industry’s highest frequency
3A device. The MIC4722 is the latest member of Micrel’s MHz operating, small
footprint non-synchronous buck regulator family that also includes the MIC2207
and MIC2208. The device targets applications that require high operating
frequencies, such as the next generation xDSL modems and satellite radios.
The entire family of solutions target applications in the broadband
communication, low power FPGA, printer, HDD, multimedia set top box and other
consumer electronics markets. The MIC4722 is available in volume and pricing
starts at $1.70 for 1K quantities.

"The need for less expensive external components and smaller solution
footprints continue to be key for designers across many applications and
markets," noted Ralf Muenster, Micrel’s marketing director for power products.
"Micrel’s MIC4722 buck regulator’s industry leading 2.7MHz operating frequency
allows customers to use the combination of a 470nH inductor and a 4.7mF output
capacitor in their application, creating by far the smallest output filter
combination available in the market today."

The MIC4722 features an ultra-fast operation and a proprietary internal
compensation which allows for extreme transient response and the usage of the
smallest and most cost-effective LC components in its class. A low resistance
integrated p-channel MOSFET enables the chip to deliver up to 3A with more
than 94 percent efficiency. The output voltage can be adjusted down to 1V and
can operate with a maximum duty cycle of 100 percent for use in low dropout
conditions. The P-MOSFET also does away with the need for a sense resistor to
provide a current limit, consequently further reducing the need for external
components.
