The Silan SC46166 is a 500 kHz, high‑efficiency boost DC‑DC converter with low‑voltage start‑up and ultra‑low quiescent current.
The SC46166 is a miniature, flat‑pack boost DC‑DC converter designed for battery‑powered applications such as MP3 players, digital cameras and PDAs. It operates from a single AA cell (0.85 V start‑up) and provides a regulated output of 2.5 V to 6 V at up to 100 mA.
The device integrates error amplifiers, oscillators, current comparators and logic drivers, eliminating the need for external compensation components. It features a power‑save mode that draws only 20 µA static current and includes over‑temperature and ESD protection. This manual is written in Chinese.
