⚠️ Many “free” schematic sites still host the old, flawed version. Compare the feedback divider (resistors R126/R127) – the updated version shows R126 = 10kΩ , not 12kΩ.
The ILPI-354 V.A is an integrated power supply and LED driver board (PCB #491A011H1400H03) used in several Dell E-Series and SE-Series monitors, including the E2016HL and SE2218HV. The circuit features a primary switching stage, typically utilizing components like the LD75xx or OBxxxx PWM ICs, and a secondary stage providing +5V and +12V/19V outputs.
