The dual-channel booster LT3486 produced by Linear Technology can drive 16 white light LEDs with a constant current(each channel has 8 serial LEDs), it can not only provide with PWM dimming, but also maintain the light color of the LED. It is fitted in portable electric equipment, car screens and other situations. LT3486 dims by controlling the working period of PWM, and the dimming range is 1000:1. It keeps the even LED brightness by the current mode and solid frequency.
