Micrel Tunes In With New Fully Integrated, Wide-Input Range Boost Regulators
Micrel Inc. introduced the MIC2605/6, two new wide-input range integrated switch and Schottky diode boost regulators operating at 1.2MHz (MIC2605) and 2MHz (MIC2606). Both devices supply up to 0.5A switch current. The devices, which complement Micrel’s recently introduced MIC2601/2 family, are aimed at TV-tuners, broadband communications, TFT-LCD bias supplies, positive output regulators, SEPIC converters, DSL applications and local boost regulators.
"Micrel’s latest boost regulators are ideally suited to meet today’s space-sensitive applications by integrating the power switch and the Schottky diode in the IC," noted John T. Lee, Director of Non Portable Power, Micrel. "These are high-power density boost regulators offering 0.5A of switch current and running at 1.2 and 2MHz. Our customized processes and novel design features enable us to offer best-in-class boost regulator solutions to our customers."
The MIC2605/6 are wide-input range (4.5-20V) integrated switch and Schottky diode boost regulators with output voltage as high as 40V. The devices are ideal for multiple applications.
The integrated 0.5A switch and Schottky Diode bring several key benefits to the designer including high power density and low external component count, as well as a low BOM cost. The devices offer up to 2MHz PWM frequency, and feature high efficiency. Enhanced stability comes from the use of a small ceramic capacitor, which contributes to a low external component count and associated BOM cost. The solutions come in a small footprint, reliable Pb-free 2 x 2mm MLF®-8 package.
The ICs are currently available in volume quantities, with pricing starting at $0.98 for 1K quantities.
