Overview
Datasheet Power Supply IC Series for TFT-LCD Panels Multi-channel System Power Supply IC + Gamma Buffer BD8162AEKV General Description The BD8162AEKV is a system power supply IC that provides control 6 power supply channels and 4 gamma output channels + VCOM required for TFT-LCD panels on a single chip.
All channels have built-in control input and Power-Good output functions, enabling free sequence control setting just by changing channels.
In addition, the BD8162AEKV is a user-friendly IC incorporating input switch, short-circuit protection, and protection detection output circuits.
