Micrel Expands High Power Density Family with Introduction of MIC22400
SAN JOSE, Calif., Feb. 25 /PRNewswire-FirstCall/ -- Micrel Inc.,
(Nasdaq: MCRL), an industry leader in analog, high bandwidth communications
and Ethernet IC solutions, today introduced a new member to its high power
density family of products, a fully-integrated 4A synchronous buck regulator,
the MIC22400 for powering systems from 3.3V and 5V supply rails. With
operating frequency programmable from 800KHz to 4 MHz, the IC features
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 solution is 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
MIC22400 is currently available in volume quantities with pricing starting at
$2.54 for 1K quantities.
"Ease-of-use, small size, high efficiency and high integration are key
drivers for today's demanding power designs," noted Andrew Cowell, Micrel's
vice president of marketing for analog products. "The MIC22400 delivers 4A at
high efficiency while setting new standards in terms of small footprint and
increased functionality."
The MIC22400 features fully integrated 60mOhm P-FET and 35mOhm N-FET
switches that deliver a 4A output current with an input voltage range of
2.6-5.5V. The device has an adjustable output voltage down to 0.7V and
provides efficiencies of up to 95 percent. A proprietary, patent-pending
internal compensation scheme makes the devices extremely easy to use. The
MIC22400 requires very few external components and operates at a high fixed
switching frequency, which in turn, reduces the size of passive components.
The built-in sequencing/tracking feature enables reliable power up/down in
multi-rail ASIC/FPGA applications. The device also offers an ultra-fast
transient response, allowing the use of small output capacitors, and thermal
shutdown, current limit protection and a junction operating range from -40-deg
C to +125-deg C. The IC is available in a 20-pin 4mm x 3mm MLF(R) with a
thermally-enhanced Epad TSSOP available by the end of Q1, 2008 .
