Allegro MicroSystems, Inc. Announces New Addition to their Family of Regulators For Satellite Receivers and LCD TV “Combo” Designs

4月 10, 2012

Small Ceramic-Cap-Based Solution Adds Key Voltage Needed for Japan Market

Worcester, MA – Allegro MicroSystems, Inc. expands their family of Low Noise Block Regulators (LNBRs) designed for satellite receivers in Set Top Boxes and LCD TVs. Allegro’s A8303 is a single channel LNBR that utilizes small ceramic capacitors (instead of electrolytic) within the boost regulator control. The end result is a lower-profile solution that is a key requirement in LCD TV designs. Furthermore, the device can provide a key output voltage setting (15.6 V) to accommodate Japan-specific design requirements.

Allegro’s latest device offers industry-leading internal protection and robustness, an integrated boost MOSFET, current sensing, and compensation which simplifies the design and minimizes components and PCB size. The A8303 has a low supply current to save energy, high level of diagnostics, and a resistor-programmed output current limit to minimize the boost inductor/diode size and costs.

The A8303SESTR-T is available in a 4 x 4 TQFN/MLP-20 package.
