Other Parts Discussed in Thread: LM3431
Hi Ti
We are using the LM3431 to drive the TFT backlight, and the backlight structure consists of 11 sets in series with 4 LEDs in parallel in each set, with a current of 100mA for each set.
The input voltage is 24V, but the measured output voltage is 37.5V, and the current is 0mA. Can you please help me determine if there is a design error in the circuit?lm3431-circuit.pdf
