Power Supply IC Series for TFT-LCD Panels  
Single-channel Source Voltage  
OutputPowerSupply+GammaBufferAmpICs  
BD8151EFV,BD8157EFV  
No.09035EBT11  
Description  
The BD8151EFV,BD8157EFV power supply IC are designed for use with TFT-LCD panels. It incorporates a built-in source  
voltage step-up switching regulator and gamma correction buffer amp. The combination of a source power supply and  
gamma correction buffer on a single chip delivers significant cost savings.  
Compatible with input voltages from 2.5 V to 5.5 V (BD8151EFV), 2.1 V to 4.0 V (BD8157EFV), the IC supports low-voltage  
operation and reaches over 85% efficiency with a 2.5 V input, contributing to low power consumption designs.  
Features  
1) Single-chip implementation of a source power supply and gamma correction buffer  
2) Support for low-voltage operation, with input voltages from 2.5 V to 5.5 V (BD8151EFV)  
2.1 V to 4.0 V (BD8157EFV)  
3) Built-in 1.4 A, 0.2 low-voltage FET  
4) Switchable step-up DC/DC switching frequencies: 600 kHz/1.2 MHz  
5) Current mode PWM control  
6) Under-voltage lockout protection circuit  
7) Built-in overcurrent protection circuit  
8) Built-in thermal shutdown circuit
