DY XXSXXX-1W series products are isolated voltage regulation series products launched by Yaohua, with the advantages of small size, high efficiency, high isolation voltage, high reliability and low price. It is suitable for digital signal processing circuits and analog circuits with low voltage stability requirements, especially for distributed power supply systems and circuits with low power supply.
The DY XXSXXX-1W series is an isolated fixed‑output DC‑DC converter offering small size, high efficiency, high isolation voltage, and low cost. It is suited for digital signal processing circuits and analog circuits with modest voltage‑stability requirements, especially in distributed power‑supply systems.
The manual lists key electrical characteristics such as 1000 VDC insulation strength, 1 W full‑load output power, selectable output voltages from 3.3 V to 30 V, and typical efficiencies of 80 % (minimum 70‑75 %). It also includes operating notes on load conditions, short‑circuit protection, ripple control, and guidelines for parallel operation of multiple converters. This manual is written in Chinese.
