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.
