This 16 channel LED driver circuit is designed using LT3754 LED driver with a step-up DC DC controller designed by Linear Technology and is capable of driving up to 45V of LEDs.
Each channel of the LT3754 16 channel LED driver circuit contains an accurate current sink with ±2.8% current matching. If are used high current Leds channels can be paralleled .
The LT3754 16 channel LED driver circuit allows a PWM dimming range up to 3000:1 and an analog dimming range up to 25:1. Operating frequency of the LT3574 16 channel LED driver can be programmed from 100kHz up to 1MHz using just a simple resistor or an external clock .
