High-performance LED driver touts cost edge

Product Review – Supertex bills its HV9911 current-mode controller as one that provides equal or better performance at a decidedly lower price than competing devices, focusing for comparison mainly on products from Linear Technology’s LED driver portfolio, which include the LT3474, LT1618, LT3486, and LTC3783. The second advantage is the device’s high-voltage regulator, and thus the chip can be powered from a 110-volt rectified (DC) input.
