The BD8153EFV is a system power supply IC for TFT panels. It is a single-chip IC that provides the four voltages required for TFT panels, namely logic voltage, source voltage, gate high-level voltage, and gate low-level voltage, thus constructing a TFT panel power supply with minimal required components.
The BD8153EFV is a system power‑supply IC designed for TFT‑LCD panels. It integrates a step‑up DC/DC converter, a 3.3 V regulator, charge‑pump circuits, and a gate‑shading function, delivering four required voltages with minimal external components.
The document lists electrical characteristics, absolute maximum ratings, pin functions, block diagrams, and design guidelines such as coil inductance selection, output capacitor sizing, and starting‑sequence timing. Application examples include liquid‑crystal TVs, PC monitors, and other TFT‑LCD devices.
