BD83854GWL  
General Description  
Key Specifications  
BD83854GWL is a step-up 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.
