Ilpi-354 V.a Schematic -

: Typically provides a regulated 5V DC supply to the main control logic board and a higher voltage (around 17.5V–18V ) for the LED driver circuit.

Often uses an IC like the SG6841 or similar to manage switching and regulate output voltages (typically 5V for logic and 12V-14V for the inverter). Ilpi-354 V.a Schematic
