The LT3465AES6#TRPBF by Analog Devices is a versatile step-up DC/DC converter specifically designed for driving multiple LEDs from a single Li-Ion cell or other low voltage sources. It can drive up to six LEDs in series, ensuring identical LED currents without the need for ballast resistors. The device integrates a Schottky diode, simplifying external component requirements.
Key electrical specifications include an input voltage range of 2.7V to 16V and a maximum output voltage of 30V. The LT3465 variant switches at 1.2MHz, while the LT3465A switches at a higher 2.4MHz, allowing for the use of small external components. Efficiency is high, reaching up to 81% for the LT3465 and 79% for the LT3465A. It requires only a small 0.22 µF output capacitor for typical applications.
This LED driver is available in a low-profile, 1mm height 6-lead SOT-23 (ThinSOT) package, making it suitable for space-constrained applications. Features include automatic soft-start (LT3465), open LED protection, and one-pin shutdown and dimming control. Applications include cellular phones, PDAs, digital cameras, MP3 players, and GPS receivers.
