Universal, High Brightness LED Driver IC From Supertex Offers Increased 
Flexibility and Higher Efficiency 
The Enhanced HV9910C Offers Simple, Cost-Effective Design Solution 
SUNNYVALE, CA -- (Marketwired) -- 04/25/13 --  Supertex, Inc.
(NASDAQ: SUPX) today introduced HV9910C, an open loop, current mode,
universal high brightness LED driver IC. It is ideal for general and
decorative LED lighting, flat panel display backlighting, and other
DC/DC or AC/DC input based applications. 
HV9910C is an enhanced drop-in replacement to the HV9910B, designed
to convert high voltage supplies (85V - 265VAC rectified) or (15V -
450VDC) to a constant current source for powering a string or a
combination of strings of high brightness LEDs. It can be programmed
to operate in either a constant frequency or constant off-time mode
and includes a 15 - 450V linear regulator which allows it to work
from a wide range of input voltages without the need for an external
low voltage supply. 
"HV9910C requires only three external components (apart from the
power stage) to produce a controlled LED current making it an ideal
solution for low system cost," states Alex Mednik, Application
Engineering Director at Supertex. "Furthermore, the low component
count allows for higher reliability and minimum board space."  
HV9910C is available in a lead(Pb)-free/RoHS compliant 8L SOICN and
16L SOICN package (HV9910CLG-G and HV9910CNG-G, respectively).
Samples are available from stock. Lead-time for production quantities
is 4-6 weeks, ARO. Pricing is USD$0.36 each for the HV9910CLG-G and
USD$0.46 each for the HV9910CNG-G in 1K quantities.
