Fig below is from the LCD datasheet. I think each string requires 20ma with approx 16V (5*3.2) of drop across each string. LCD has separate anode and cathode pins for each string.
Input voltage is 4.5V to 6V
5V level PWM input for dimming
What are the suitable parts with OVP or open LED protection? We prefer SOT23-5 or SOT23-6 package.
Can both the strings be connected in parallel to the boost regulator output and fb pin? If not, how it should be connected to drive both the strings from a single driver?
-Thanks
