Description
The AS3693B1 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.
Features
- include thermal shutdown as well as open and short LED detection. All circuit parameters are programmable via I2C or SPI interface. 2 Key Features
16 Channel LED driver Output current only limited by external transistor Output voltage 0.4V to 50V Absolute current accuracy +/- 0.5% Output slew rate programmable Current programmable with external resistor Linear current control with 8 - bit DAC Linear current control with external analog voltage Digital current control with 16 independent PWM gene.
