Microsemi Debuts New LX1995 LED Driver

Microsemi Corp. (Irvine, CA), a manufacturer of discrete semiconductors and power management integrated circuits, announced a new miniature LED driver for powering LEDs in hand-held display applications that include wireless phones, pagers, digital cameras, GPS receivers and personal digital assistants.

Designated the LX1995, the new step-up, boost converter is available in a 1 mm, five-pin, thin-shrink small-outline (TSOT) package. The LX1995 utilizes small-sized external inductor and filter capacitors to conserve board space for hand-held designs. The LX1995 driver is available in two options for switch current specifications: the LX1995-1 with a switch current of 325 mA for applications of up to six LEDs, and the LX1995-2 with a switch current of 500 mA for applications up to 10. It also is designed to provide automatic brightness control of LED displays when teamed with Microsemi’s visible light sensors, such as the LX1971 and LX1972.

The LX1995 is also available in the 1.3 mm high, SOT-23 package for applications not requiring the thinnest height. Both versions are available for immediate sampling and delivery, with 10,000-quantity pricing at $0.58 for the TSOT and $0.50 for the SOT-23 version.
