LISTED UNDER:

boost regulator ICsMicrel introduced the MIC2605/6, two wide-input range integrated switch and Schottky diode boost regulators operating at 1.2 MHz (MIC2605) and 2 MHz (MIC2606).  Both devices supply up to 0.5 A switch current. The devices, which complement the company's 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. The MIC2605/6 feature a wide-input range (4.5–20V) with output voltage as high as 40V. The integrated 0.5A switch and Schottky diode offer the designer high power density, low external component count, up to 2 MHz PWM frequency, and high efficiency. Enhanced stability comes from the use of a small ceramic capacitor. The ICs are available in volume quantities, with pricing starting at $0.98 for 1K quantities.
