Micrel Launches Industry's Smallest Fully-Integrated 6A Synchronous Buck Regulators For 3V and 5V Supply Rails

SAN JOSE, Calif., Sept. 27 /PRNewswire-FirstCall/ -- Micrel Inc., (NASDAQ:MCRL) , an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today introduced a family of the industry's smallest fully-integrated 6A synchronous buck regulators, the MIC2260x series for 3V and 5V supply rails. Operating at 1MHz (MIC22600) or at 4 MHz (MIC22601), the ICs feature built-in sequencing, tracking and ramp control -- enabling all power-up sequencing and tracking protocols. Targeted at the communications, computing peripherals, and high-end consumer markets, the solutions are ideal for servers/routers, HD DVD recorders, wireless base stations, FPGAs, DSPs, and low voltage ASICs, as well as other high power density applications. The MIC22600 is currently available in volume quantities with the MIC22601 version available starting in October, 2007. Pricing starts at $2.68 for 10K quantities.

"Ease-of-use, small size, high efficiency and high integration are key drivers for today's demanding power designs," noted Ralf Muenster, Micrel's marketing director for power products. "The MIC2260x are 6A, high efficiency, current mode buck regulators featuring fully integrated MOSFETs while setting new standards in terms of footprint and functionality."

The MIC2260x feature fully integrated 30mOhm P-FET and 25mOhm N-FET switches that deliver a 6A output current with an input voltage range of 2.6-5.5V. The devices have an adjustable output voltage option down to 0.7V and provide efficiencies of up to 93 percent. A proprietary, patent-pending internal compensation scheme makes the devices extremely easy to use. The MIC2260x require very few external components and operate at high fixed switching frequencies, which in turn, reduce the size of passive components. The built-in sequencing/tracking feature enables reliable power up/down in multi-rail ASIC/FPGA applications. The devices also feature an ultra-fast transient response, thermal shutdown and current limit protection, and a junction operating range from -40-deg C to +125-deg C. The ICs are available in a 24-pin 4mm x 4mm MLF(R).
