{1187A} LED driver function explained, failure root cause analysis

In this video number {1187A} LED driver function explained, failure root cause analysis. I explained working principle of BP2864 LED driver IC for 20 LED lights. i also shared FA (failure analysis), RCA (root cause analysis or RCFA (root cause failure analysis), i diagnosed the the exact root cause of the faiure of the led driver circuit. BP2864XJ is an external OVP buck LED constant current driver chip. The chip works in the critical continuous mode of inductor current and is suitable for non-isolated buck LED constant current power supply with full range input voltage of 85Vac~265Vac. The IC ROVP pin has Enable function, which is suitable for switch color adjustment and induction lampapplications. The BP2864XJ chip integrates a 500V power switch, uses gate demagnetization detection technology and high-voltage JFET power supply technology, and does not require VCC capacitors and startup resistors, making its peripheral devicessimpler and saving peripheral costs and volume. The BP2864XJ chip has a built-in high-precision current sampling circuit and constant current control technology toachieve high-precision LED constant current output and excellent line voltage regulation. The chip works in the inductorcurrent critical mode, and the output current does not change with the change of inductance and LED operating voltage,achieving excellent load regulation. BP2864XJ has multiple protection functions, including LED short circuit protection, chip power supply undervoltageprotection, external OVP, chip temperature overheating regulation , etc. You are Invited to Join Haseeb Electronics    / @haseebelectronics   Please check other videos 20 watt LED light simple repair    • {1187} 20 watt LED light simple repair   Barcode scanner repair,    • {1188} Barcode scanner repair, Panda ...   Truck weight scale repair    • {1186} Truck weight scale repair   Trans-Auto generator controller has no display    • {1175} Trans-Auto generator controlle...   24 volt SMPS repair, No output voltage    • {1181} 24 volt SMPS repair, No output...   SMPS no output    • {966} SMPS Is not working, not turnin...   SMPS step by step repair tutorial    • {528} How To Repair SMPS || SMPS Repa...   How to download circuit diagram, service manual    • {558} How To Download Circuit Diagram...   Transistor, IGBT, MOSFET equivalent    • {233} How to find Equivalent or Subst...   Broken plastic gear repair    • {679} How To Repair Broken Plastic Ge...   You can Follow me on :- Instagram:   / haseebelect   Facebook: https://web.facebook.com/profile.php?... #leddriver #circuitdiagram #explained
