LT3518EUF Description

Short technical summary and product information.

The LT3518EUF is a versatile LED driver IC manufactured by Analog Devices, designed for driving LEDs in various applications. It features a robust 2.3A, 45V internal switch, enabling efficient operation in boost, buck, and buck-boost modes. The device supports a high 3000:1 True Color PWM dimming ratio and an additional 10:1 analog dimming via the CTRL pin, allowing for precise light intensity control.

 

With a wide input voltage range of 3V to 30V and transient protection up to 40V, the LT3518EUF is suitable for demanding environments. It operates with a programmable switching frequency from 250kHz to 2.5MHz, allowing optimization for efficiency or component size. The LED current is externally programmable using a 100mV high-side current sense resistor.

 

Available in compact 16-lead QFN (4mm x 4mm) and 16-pin TSSOP packages, the LT3518EUF provides a complete solution for constant-current and constant-voltage LED driving applications, including display backlighting, automotive lighting, and general illumination.
