Practical circuit diagram based on LT3468 dual output boost LED driver

This circuit is a practical circuit based on the LT3486 dual-output boost LED driver . It drives two strings of LEDs with a constant current of 100mA, and the LED voltage is up to 36V. This boost converter uses a small voltage sense resistor in series with the LED string and PWM dimming MOSFET and has high efficiency. The dual-channel LED driver drives two LED strings of 20 LEDs over a battery voltage range of 9 to 16V while keeping the maximum switching voltage below the IC's 42V rating.
