Linear Technology LT3465/LT3465A Boost Converter Datasheet
The LT3465 and LT3465A are step‑up DC/DC converters designed to drive up to six LEDs in series from a Li‑Ion cell. They integrate a Schottky diode, provide automatic soft‑start, open‑LED protection, and dimming control. The LT3465 switches at 1.2 MHz, while the LT3465A operates at 2.4 MHz, allowing the use of very small external components.
Typical applications include cellular phones, PDAs, digital cameras, MP3 players, and GPS receivers. Recommended external components are a 22 µH inductor and a 0.22 µF output capacitor. The devices are offered in a low‑profile 6‑lead SOT‑23 (ThinSOT) package.
