SUNNYVALE, CA -- (Marketwire) -- 01/24/13 -- Supertex, Inc. (NASDAQ: SUPX) today introduced HV9803, an open loop, average-mode, current control LED driver IC operating in a constant off-time mode. It is well suited for backlighting LCD panel applications such as TVs and monitors.



The IC features +/-2% current accuracy, tight line and load regulation of the LED current without any need for loop compensation or high-side current sensing. Its auto-zero circuit cancels the effect of both the input offset voltage and the propagation delay in the current sense comparator. The IC features linear and PWM dimming modes. The HV9803 is equipped with a current limit comparator for hiccup-mode output short circuit protection. It also features a programmable input under-voltage shutdown.





"By utilizing Supertex's patented average-mode current sensing technology, HV9803 provides a low-cost LED backlighting solution for an LCD panel," states Alex Mednik, Director of Application Engineering at Supertex. "The 2% accurate current control of this IC ensures uniformity of the LED backlight."



HV9803 is available in a lead(Pb)-free/RoHS compliant SOIC-8 package (HV9803LG-G). Samples are available from stock. Lead-time for production quantities is 4-6 weeks ARO. Pricing is US$0.41 for the HV9803LG-G, in 1K quantities.
