Linear Technology LT3494/LT3494A Boost Converter Manual
This manual describes the LT3494 and LT3494A micropower low‑noise boost converters with integrated power switch, Schottky diode, and output‑disconnect circuitry. It lists key features such as low quiescent current, non‑audible switching frequency, wide input (2.3 V‑16 V) and output ranges, and integrated dimming capability.
The document provides absolute maximum ratings, package dimensions, pin descriptions, electrical characteristics, and design guidance for inductors, capacitors, and feedback networks. Application notes, typical performance curves, and example circuits are included to help designers implement the devices in OLED power supplies, MP3 players, and other low‑power applications.
