LT8374/LT8374-1 Series

The LT8374/LT8374-1 is a high efficiency, monolithic, synchronous step-down DC/DC converter with fixed-frequency and peak current control. The LED current is programmed by a resistor from CTRL pin to ground or by applying a PWM signal to the CTRL pin. The current sense amplifier has a wide common mode range from 0V to VIN, making the LT8374 ideal for matrix applications. An output voltage limit can be set with a resistor from ISP pin to FB pin.The switching frequency is set at 330kHz/2MHz and can be synchronized to an external clock applied to the SYNC/SPRD pin. With the optional spread-spectrum frequency modulation enabled, the frequency varies from 100% to 125% to reduce EMI.Additional features include an optional 0.2nF/0.9nF internal compensation capacitor and thermal shutdown.APPLICATIONSAutomotive LightingMatrix LED LightingGeneral Purpose LED DriverCurrent Sources
