The LT3465ES6#TRMPBF is a step-up DC/DC Converter designed to drive up to six LEDs in series from a Li-ion cell. Series connection of the LEDs provides identical LED currents and eliminates the need for ballast resistors. This device integrates the Schottky diode required externally on competing devices. Additional features include output voltage limiting when LEDs are disconnected, one-pin shutdown and dimming control. The LT3465 switches at 1.2MHz, allowing the use of tiny external components. 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.

• Internal soft-start
• Inherently matched LED current
• No external Schottky diode required
• Open LED protection
• Requires only 0.22μF output capacitor
