The is a critical power supply board primarily utilized in various Dell LCD monitor series , including the E1916HV, E2216HV, and SE2218HV. This board is responsible for converting AC input into regulated DC voltages needed to power both the logic board and the LCD backlight. Technical Overview & Specifications ILPI-354 V.A
While it is always best to replace a component with an exact original part, the repair logs show that several successful substitutions have been made. These are outlined in the schematic update table above and include: ilpi354 va schematic upd
Uses an optocoupler (e.g., PC817) paired with a TL431 precision shunt regulator to cross the primary-secondary isolation barrier safely. This keeps the secondary output rails locked at exactly 5V and 12V/19V, independent of grid fluctuations. 3. LED Backlight Driver Circuit (Cold Side) The is a critical power supply board primarily
The board design commonly features a PWM driver IC, power MOSFETs, and high-voltage electrolytic capacitors. Common Faults and Diagnostics These are outlined in the schematic update table
: Serves as the primary power converter for Dell monitors such as the Dell SE2216H , Dell E1916HV , E2016HL, E2316HF, and Dell SE2218HV . Voltage Rails :
