| Manufacturer | austriamicrosystems |
| Description | The AS3833 is a 6 channel high precision LED controller with PWM input for driving external bipolar transistors in LCD-backlight panels, optimized for 2D and 3D operation. The integrated step-up controller provides the necessary output voltage for the LED string supply. The SMPS feedback control optimizes the power efficiency by adjusting the LED string supp. |
