PDF for BD9893F, 143 KB, filed as a schematic. The code follows ROHM's BD-series numbering for power and driver ICs, with the F suffix usually marking the package; the name says nothing more, so it is most likely the datasheet for this chip. Repairers use it to look up pin functions and typical application circuits when checking a part on a TV or monitor power or backlight board, for example confirming supply voltage and output switching. Check the marking on the chip before relying on the pinout. Opens in any PDF viewer.
