  • 描述

    The LT ® 3465/LT3465A are step-up DC/DC converters designed to drive up to six LEDs in series from a Li-Ion cell. ®The LT 3465/LT3465A boost DC/DC converter is designed to drive up to 6 series LEDs from a lithium-ion battery. Series connection of the LEDs provides identical LED currents and eliminates the need for ballast resistors. These devices integrate the Schottky diode required externally on competing devices. Additional features include output voltage limiting when LEDs are disconnected, onepin shutdown and dimming control. The LT3465 has internal soft-start. The LT3465 has an internal soft-start.

    The LT3465 switches at 1.2MHz, allowing the use of tiny external components. The LT3465 switches at 1.2MHz, allowing for the use of slim external components. The faster LT3465A switches at 2.4MHz LT3465A. Constant frequency switching results in low input noise and a small output capacitor. Just 0.22µF is required for 3-, 4- or 5-LED applications. 0.22μF only requires 3-, 4-, or 5-LED applications.

    The LT3465 and LT3465A are available in low profile (1mm) 6-lead SOT-23 (ThinSOT™) packages. The LT3465 and LT3465A are available in a low-profile (1mm) 6-pin SOT-23 (with ThinSOT™) package.
