The LT3743EUFD is a fixed-frequency, synchronous step-down DC/DC controller specifically designed for driving high-current leds. The average current mode controller will maintain the inductor current regulation function within a wide output voltage range of 0V to (VIN - 2V). The following are its core features:
PWM dimming offers a dimming ratio as high as 3000:1
CTRL_SEL dimming offers a dimming ratio of up to 3000:1 between any currents
Three-state current control for color mixing
Current regulation accuracy of ±6%
Input voltage range: 6V to 36V
Average current mode control
The maximum recovery time between any current regulation states is 2μs
Shutdown current <1μA
Output voltage regulation and open-circuit LED protection
Heat resistance enhanced 4mm x 5mm QFN package and 28-pin FE package
By adopting load capacitors that perform switching operations externally, the LT3743EUFD can change the modulated LED current level within a few μs, thereby providing accurate and high-speed PWM dimming between two current levels. The switching frequency can be set within the range of 200kHz to 1MHz through an external resistor on the RT pin.
Other features of the LT3743EUFD include voltage regulation and overvoltage protection functions (set using a voltage divider connected between the output terminal and the FB pin). The overcurrent protection function is provided and set by the CTRL_H pin.
