Micrel Inc. has released a family of wide-input range integrated switch boost regulators. The MIC2601 and MIC2602 operate at 1.2MHz and 2MHz, respectively, and can both 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 devices operate over a wide input voltage range (4.5V to 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.

"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."

Both MIC2601/2 devices are available in a small footprint, highly reliable, Pb-free 2mm x 2mm MLF-8 package. The ICs are currently available in volume quantities, pricing starts at $1.14 for 1,000 quantities.
