Boost WLED Driver for Backlights

General Description The  G5966L/G5966  is  a  6-channel  boost  WLED  driver  for  backlight  applications.  It  features  a  high-performance  boost converter, six channel current sink with 3% cur-rent  matching  and  accuracy,  and  PWM  brightness  dimming control.  

The boost converter automatically provides the regulated output  voltage  for  the  WLED  backlight  without  the  need  to  calculate  the  output  for  different  LED  types.  The  switching  frequency  is  1MHz.  It  also  integrates  a  40V  NFET that provides high output power.

The 6-channel current sink is ideal for constant current driving,  and,  well  matched  less  than  3%  (typical).  To  set the maximum driving current, the ISET pin is used to  determine  reference  current.  Each  channel  of  the  current sink is set to 1000 times of this reference cur-rent. A PWM pin can be used for PWM dimming.

The  G5966L/G5966  provides  many  protection  schemes  to  avoid any abnormal operation. Over current protection is  designed  to  protect  internal  NFET.  It  also  provides  over  voltage  and  over  temperature  protection.  The  G5966L  can  detect  open  or  short  LED  and  offer  pro-tections.

The  G5966L/G5966  is  available  in  a  16-pin  3x3mm  TQFN  package.
