LTC Offers New LTC3450 Triple-Output Power Supply

April 01, 2004 by Jeff Shepard

Linear Technology Corp. (LTC, Milpitas, CA) announced its LTC3450 power converter solution for small (2 in to 5 in) thin-film transistor (TFT) liquid crystal display (LCD) panels. The LTC3450 operates from an input-voltage range of 1.5 V to 4.6 V, enabling it to accommodate multi-cell alkaline/nickel-metal hydride batteries as well as single-cell, lithium-ion.

The LTC3450 can deliver up to 10 mA for AVDD, and 500 µA for both VGL and VGH. The LTC3450 achieves efficiencies greater than 90 percent on an output since the primary boost converter uses a synchronous rectification topology. Quiescent current is only 75 µA, providing maximum battery life, and its 3 mm x 3 mm x 0.75 mm QFN package enables a tiny, low-profile footprint.

The LTC3450 is available from stock in a 3 mm x 3 mm QFN package. Pricing starts at $2.50 each for 1,000-piece quantities.
