Allegro MicroSystems, Inc. Introduces Simple Five-Pin 1.2 MHz Step-Up Converter
A8483 serves as a general-purpose boost regulator for several applications

Worcester, MA, July 22, 2005 — Allegro MicroSystems, Inc. announces the release of the A8483 1.2 MHz Step-Up Converter for Display Bias Supply. This simple five-pin step-up converter can be used as a general-purpose boost regulator for a multitude of applications. It is ideal for battery-powered applications, but can also be used in applications such as plasma or LCD TV bias.

Allegro's newest step-up converter is a 1.2 MHz current-mode step-up dc-to-dc converter. It includes an integrated 36 V FET and comes in a small 3x3 5-lead thermally enhanced MLP/TDFN lead- (Pb) free package. Input voltage can range from 2.5 V to 10 V when connected directly to a battery or input rail. Input voltage can range from 0.9 V to 18 V when an external bias supply is connected to the A8483. Output voltage can be set up to 35 V. Smaller external components and the integrated switch reduce component count and footprint for a variety of applications.

Ideal for various end applications including portable battery-powered equipment, cellular phones, PDAs, camcorders, personal stereos, MP3 players, cameras, mobile GPS systems and HD TVs, the A8483 is supplied in a five-pin 3 mm x 3 mm MLP/TDFN package.
