LED Driver
Microsemi announces a miniature LED driver for powering LEDs in handheld display applications that include wireless phones, pagers, digital cameras, GPS receivers and PDAs. Designated the LX1995™, the step-up boost converter is available in a 5-pin package, the 1.0 mm high Thin Shrink Small Outline TSOT. The driver utilizes a small external inductor and filter capacitors to conserve board space for handheld designs. The driver is available in two options for switch current specifications: the LX1995-1 with a switch current of 325 milli-amps for applications of up to six LEDs; and the LX1995-2 with a switch current of 500 milliamps for applications up to ten. It also is designed to provide automatic brightness control of LED displays when teamed with Microsemi's visible light sensors.
