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.


SM4186 IC is installed in the LSC320AN10-H03 Samsung LCD panel; following that panel, the schematic circuit diagram of SM4186 IC is designed and published below; the circuit design is slightly different from Samsung's other model panel, keeping the pin configuration correct.
