Single-channel Source Voltage Output Power Supply ICs with Gamma Buffer Amp - BD8157EFV

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 2.5V to 5.5V (BD8151EFV), 2.1V to 4.0V (BD8157EFV), the IC supports low-voltage operation and reaches over 85% efficiency with a 2.5V input, contributing to low power consumption designs.
