In follow digitale satellite receiver (DVB-S2):
"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:

Google does not always search in the text of PDF files, otherwise one would find the appropriate type to this according SMD marking code.
