Texas Instruments introduces high-power LED driver

Jan. 28, 2009
Date Announced: 28 Jan 2009 Three new power management chips increase efficiency, voltage and output current in LED designs DALLAS, Jan. 23 -- Texas Instruments Incorporated (TI) introduced today a high-power DC/DC boost LED driver (TPS61500) and high-voltage DC/DC boost converter (TPS61175), and expanded its step-down DC/DC converter series with TPS62110.These devices can support input voltages of up to 18 V and feature smaller voltage references for improved LED circuit design. These energy-efficient devices are cross-functional and work across a variety of LED applications, including signage, ambient light, office light, general illumination, military, medical and sensors. Key features of the TPS61500: -- 2.9-V to 18-V input voltage range -- 3.0-A current switch with integrated FET-- Four 3-W LEDs from 5 Vin -- Eight 3-W LEDs from 12 Vin-- 200 kHz to 2.2 MHz switching frequency The TPS61500, TPS61175 and TPS62110 are available now in production quantities.
