BD8184MUV - Power-Supply

Description

The BD8184MUV is a system power supply for the TFT-LCD panels used for liquid crystal Monitors and Note Display.

Incorporates high-power FET with low on resistance for large currents that employ high-power packages, thus driving large current loads while suppressing the generation of heat.

Features

  • 1) Boost DC/DC converter; 18 V / 2.5 A switch current. (Target specification is ±1% accurate. ) 2) Switching frequency: 1.2 MHz 3) Operational Amplifier (short current 200mA) 4) Incorporates Positive / Negative Charge-pump Controllers. 5) Gate Shading Function 6) VQFN024V4040 Package (4.0 mm x 4.0 mm) 7) Protection circuits: Under Voltage Lockout Protection Circuit Thermal Shutdown Circuit (Latch Mode) Over Current Protection Circuit (AVDD) Timer Latch Mode Short Circuit Protection (AVDD SRC VGL).

Power Supply ICs for TFT-LCD Panels Multi-channel System Power Supply IC for Small to Middle PANEL BD8184MUV No.11035EAT18 Description The BD8184MUV is a system power supply for the TFT-LCD panels used for liquid crystal Monitors and Note Display. Incorporates high-power FET with low on resistance for large currents that employ high-power packages, thus driving large current loads while suppressing the generation of heat. A charge pump controller is incorporated as well, thus greatly reducing the number of application components. Also Gate Shading Function is included. Features 1) Boost DC/DC converter; 18 V / 2.5 A switch current. (Target specification is ±1% accurate.) 2) Switching frequency: 1.
