Quenching The Thirst For High Power Density, Micrel Unveils First Ever 40V Wide Input Range Boost Regulator Solution

Devices Feature Up To 40V Output Voltage And 2MHz PWM Frequency

            San Jose, Calif., Oct. 27, 2008 — Micrel Inc., (Nasdaq:MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today rolled out a new product line, a family of wide-input range integrated switch boost regulators.  The MIC2601 operates at 1.2MHz and the MIC2602 at 2MHz.  Both can supply up to 1.2A switch current.  The MIC2601/2 are aimed at multimedia STB/antenna/tuners, broadband communications, TFT-LCD bias supplies, bias supplies, positive output regulators, SEPIC converters, DSL applications and local boost regulators.  The ICs are currently available in volume quantities, pricing starts at $1.14 for 1K quantities.  Samples can now be ordered on Micrel's web site at:  http://www.micrel.com/ProductList.do . 

"Micrel's latest integrated switch boost regulators satisfy designers need for superior power solutions.  These high-power-density boost regulators, operating at 1.2 and 2MHz, are ideal for a wide variety of broadband, power supply and multimedia applications," noted John T. Lee, marketing director Non Portable Power, Micrel.  "Our customized processes and novel design features enable us to offer best-in-class boost regulators for customers."

These devices, offered by Micrel for the first time, operate over a wide input voltage range (4.5V — 20V) and boost output voltages to as high as 40V.  These easy-to-use regulators feature a built-in 1.2A switch, resulting in low external component count as well as low BOM costs.  Offering up to 2MHz PWM frequency, these devices are highly efficient and require only the smallest external components.  Enhanced stability comes from the use of a small ceramic capacitor.  Both MIC2601/2 devices are available in a small footprint, highly reliable, Pb-free 2mm x 2mm MLF®-8 package.
