The DY series products are isolated voltage series with significant advantages, such as small size, high efficiency, high isolation voltage, high reliability and low price.
The DY XXSXXX‑W5 series from Yaohua is an isolated, fixed‑output DC‑DC converter family noted for its small size, high efficiency, high isolation voltage, and low cost. It is suited for digital signal processing circuits, low‑precision analog circuits, distributed power systems, and low‑power applications. For circuits requiring higher voltage stability or low ripple, the WDY series is recommended.
The manual details the series' general features, input and output characteristics, typical performance curves, mechanical dimensions, pin configuration, and important usage notes such as recommended load conditions, short‑circuit protection, and filter component selection for low‑noise designs. This manual is written in Chinese.
