"HD22" from "Nwe Line Electronics GmbH" (brand unknown, Made in China) PCB designation: "STB-DECODER-14-V03" The searched device (only CA1MB) is responsible for the LNB (LNC) voltage control for select the horizontal or vertical aera. Similar switching regulators are follow: http://www.ti.com/lit/ds/symlink/mc34063a.pdf http://www.onsemi.com/pub_link/Colla...MC34063A-D.PDF Google does not always search in the text of PDF files, otherwise one would find the appropriate type to this according SMD marking code. |
