Datasheet for the RZC3617BH secondary‑side synchronous rectifier controller, detailing features, electrical specs and application notes.
The RZC3617BH is a high‑performance secondary‑side synchronous rectifier controller IC designed for low‑voltage, high‑current switch‑mode power supplies. It integrates waveform‑tracking, internal low‑RDS(ON) MOSFETs and high‑voltage isolation, enabling efficient power conversion up to 100 kHz switching frequency.
The device operates from a 3.2 V to 9 V supply, offers a static current as low as 0.2 mA, and is packaged in a compact SOP‑8. Typical applications include QC 3.0 fast‑charge, 18 W PD adapters and other high‑efficiency power adapters. This manual is written in Chinese.
