The BD8157EFV is a single-channel source voltage output power supply IC with an integrated gamma buffer amplifier, specifically designed for TFT-LCD panel applications. It operates with input voltages ranging from 2.1 V to 4.0 V and achieves over 85% efficiency at a 2.5 V input, making it suitable for low-power consumption designs. The IC features a built-in 1.4 A low-voltage FET, switchable step-up DC/DC switching frequencies of 600 kHz and 1.2 MHz, and current mode PWM control. It includes essential protection features such as under-voltage lockout, overcurrent protection, and thermal shutdown. The operating temperature range for the BD8157EFV is from -40¬8C to +125¬8C, which enhances its reliability in various environments. Applications include satellite navigation systems and laptop PC TFT LCD panels.
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.
