BD8163EFV is a system power supply IC for TFT panels from ROHM Co., Ltd. A 1-chip IC providing a total of four voltages required for TFT panels, i.e., logic voltage, sauce voltage, gate high-level, and gate low-level voltage, thus constructing a TFT panel power supply with minimal components required.
The BD8163EFV is a system power‑supply IC designed for TFT‑LCD panels. It integrates a step‑up DC/DC converter, a 2.5 V regulator, charge‑pump circuits and a gate‑shading function, delivering four required voltages with minimal external components.
The note lists electrical characteristics, absolute maximum ratings, recommended operating ranges, pin assignments, block diagram and ordering information. It also describes protection features such as under‑voltage lockout, thermal shutdown and over‑current protection.
