SANYO LC4120NV Datasheet
Overview
The LC4120NV is an LCD power supply switching IC
that provides 3 input channels and 6 output channels. It is
fabricated in an 80-V high-voltage CMOS process and
features low power dissipation, high speed, and a low
output impedance. This IC is optimal for switching the
row driver LCD drive voltage in a wide range of LCD
products.
