Evaluation Kit - 34845, LED Backlight Driver, Power Supply
- This page contains information on a product that is no longer manufactured (discontinued). Specifications and information herein are available for historical reference only.
Evaluation kit for the 34845 products, which represent high efficiency, LED drivers for use in backlighting LCD displays from 10” to 17”+. Operating from supplies of 5.0 V to 21 V, the 34845 series is capable of driving up to 16 LEDs in series in each 6 strings. The LED current tolerance in the 6 strings is within ±2% and is set using a resistor to GND.
PWM dimming is performed by applying a PWM input signal to the PWM pin which modulates the LED channels directly. The integrated boost converter uses dynamic headroom control to automatically set the output voltage.
