I need to drive LEDs in LCD backlighting. My LED are in this circuit:
The backlight needs a current of 700 mA at 9 V. What driver should I use for control? According to the current peak calculation is 1.5A at 5V supply power at 79% efficiency of driver.
Can I use the circuit LD41 from STMicroelectronic?
On board I have the power branches 5V and 24V.
