Evaluation Kit - 34845, LED Backlight Driver, Power Supply
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.
