AS3693B–16 Channel high precision LED driver for LCD Backlight

AS3693B

$600.00Price
  • The AS3693B is a 16 channels high precision LED controller with build in PWM generators for driving external FETs in LCD-backlight panels. External clock and synchronizing inputs allow the synchronization of the LCD backlight with the TV picture. Local dimming and scan dimming is supported by 16 independent PWM generators with programmable delay, period and duty cycle. Three free configurable dynamic power feedback circuits make the device usable for white LED as well as RGB backlights. Build in safety features include thermal shutdown as well as open and short LED detection. All circuit parameters are programmable via I2C or SPI interface.
