Boost and Inverted Output

Power Supply for TFT-LCD Displays

BD83850GWL

General Description

Key Specifications

BD83850GWL is a boost switching regulator and charge

pump inverter for small TFT-LCD Displays. It has a wide

input voltage range of 2.5V to 4.5V that is suitable for

portable applications. In addition, its small package

design is ideal for miniaturizing the power supply.
