SAN JOSE, CA, Oct 01, 2009 (MARKETWIRE via COMTEX) -- MCRL | Quote | Chart | News | PowerRating -- Micrel Inc. (NASDAQ: MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today introduced the MIC2174, the latest, premium member of its Hyper Speed Control(TM) family of adaptive on-time controllers. The device is a high performance, first-in-its-class DC-to-DC controller capable of high delta V operation (VIN=40V, VOUT=0.8V) and can drive up to 25A of load current. The Hyper Speed Control(TM) architecture significantly reduces the required output capacitance and allows for excellent transient response. The solution is ideal for industrial equipment power supply, automotive applications, computer peripherals and distributed DC power systems. The MIC2174 is currently available in volume quantities with pricing starting at $1.00 for 1K quantities. Samples can be ordered on line at: http://www.micrel.com/ProductList.do.

"By pushing the maximum input voltage to 40V, applications that require high delta V operation can take advantage of our unique architecture," stated John T. Lee, director of power products, Micrel. "Micrel's unique Hyper Speed Control(TM) architecture offers terrific benefits like reduced BOM cost and world class transient response for applications such as industrial equipment, automotive electronics and distributed power systems."

The MIC2174 operates at 300kHz constant frequency and achieves greater than 94 percent efficiency, over a broad load range. The device is easy to use and is stable even with a zero-ESR output capacitor, making designs very robust and offering the ability to scale down external capacitors. The MIC2174 Hyper Speed Control(TM) DC-to-DC controller operates over a wide input supply range of 3V to 40V and also offers cycle-by-cycle current limiting for FET protection. While the UVLO circuitry ensures proper operation under power-sag conditions to prevent the MOSFETs from overheating, the Soft Start feature reduces the inrush current. The MIC2174 Hyper Speed Control(TM) controller is available in a 10-pin MSOP package with a junction operating range from -40degC to +125degC. All supporting documentation including the datasheet can be found on Micrel's website at: www.micrel.com
