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.
