Micrel Makes Mobile More Efficient Than Ever With New DC/DC Step Down Regulator Featuring RF PA Power Supply

SAN JOSE, CA--(Marketwire - April 26, 2010) -  Micrel, Inc. (NASDAQ: MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today introduced a high performance 600mA DC/DC step down regulator, the MIC2808. The device is intended for powering a power amplifier (PA) in mobile devices and comes with dual low noise low dropout regulators for RF chipset support. The MIC2808 is currently available in volume quantities with pricing starting at $1.09 for 10K quantities. Samples can be ordered at:

"Today's mobile devices continue to demand long battery life and small size," noted Andy Khayat, business unit director of Micrel's portable product group. "The MIC2808 gives RF system designers a tiny power supply with maximum PA efficiency regardless of user distance to the nearest cellular base station."

The MIC2808 has a 600mA, 2MHz constant frequency pulse width modulated (PWM) DC/DC regulator with DAC voltage control and 1A bypass MOSFET for high efficiency in today's most demanding mobile applications. The regulator will work in a 100 percent duty cycle mode to provide maximum power and efficiency. The MIC2808 offers dual low noise low dropout regulators which are optimized for high PSRR capability and fast turn-on times. The MIC2808 has thermal shutdown and current limit protection, is available in a 16-pin 2mm x 2.5mm MLF®, and offers a junction operating range from -40degC to +125degC.
