Three-channel LED driver launched by Supertex

A new three-channel LED driver IC has been released by semiconductor manufacturer Supertex.



Designed to provide high LED current accuracy through closed loop control of the output current, the HV9985 is ideal for application in driving multiple strings of backlight or edgelight LEDs in LCD televisions.

The product contains three peak current mode controllers providing feedback to the IC, ensuring high levels of efficiency and accuracy.

Gate drivers within the chip are optimised for driving logic level FETs at 0.25A sourcing or 0.5A sinking and each output current can be individually dimmed.

Ahmed Masood, vice president of marketing for Supertex, commented: "The HV9985's closed loop system dynamically adjusts its output voltage for excellent line and load regulation of the LED current."

Supertex recently presented its products at the 2009 UBS Global Technology and Services Conference, which was held between June 8th and June 10th at the Sheraton New York Hotel and Towers.ADNFCR-1785-ID-19244801-ADNFCR
