 SM4186 IC SCHEMATIC CIRCUIT DIAGRAM PIN FUNCTION & VOLTAGE DETAILS

SM4186 IC is a unique component for supplementary power management and signal processing in Samsung LCD TV panels. This IC has several voltage regulator circuits: the VGH charge pump circuit as the voltage boost converter and the VGL charge pump circuit as the buck converter. AVDD, HVAVDD, and VCOM circuits are integrated with SM4186 IC.

After thoroughly observing a Samsung LCD panel, I designed the schematic circuit diagram of SM4186 IC and published it below. A closer look at the circuit diagram will give a more detailed understanding. The circuit diagram of SM4186 IC will be helpful for Samsung LCD panel repair.
