Supertex' new LED driver IC with
current accuracy of +/-3%
Supertex has introduced the HV9961, an average-mode constant
control LED driver integrated circuit (IC) for driving high
bright lighting LEDs using buck topology. It is well suited
for a variety of solid-state lighting applications.
The HV9961 This provides current accuracy of +/-3% and
requires no loop compensation or high-side current sensing
because of Supertex's proprietary average mode control scheme.
The IC features hiccup-mode LED short-circuit protection
and both linear and PWM dimming.
"The HV9961 employs a novel circuit architecture to
achieve fast and accurate output current control,"
states Ahmed Masood, Vice President of Marketing at Supertex.
"With its wide input voltage range, this device is
well suited for a host of LED lighting applications such
as street, architectural, decorative, and industrial, as
well as backlighting LCD screens."
