Datasheet
Power Supply IC Series for TFT-LCD Panels
Output voltage fixed-type
Multi-channel System Power Supply IC
BD8174MUV
General Description
The BD8174MUV is a system power supply IC that
generates 6 power supply channels required by TFT-LCD
panels on a single chip.
Output voltage and sequence is fixed so that it is possible
to control output with few external components.
