To understand the context of the verification, the following changes were implemented in Ver 13 based on findings from the Ver 12 prototype:

Check the DC input or AC rectification stage. The BM5291 often utilizes a protection diode or a resettable fuse (PTC). If the board is completely dead, start here. The schematic will show you exactly where the test points (TP) for the input voltage are located. 2. The PWM Controller / Logic Core bm5291 ver 13 schematic verified
Our verification of the BM5291 Ver 13 schematic has identified several improvements and enhancements over previous versions: To understand the context of the verification, the
