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: 1.2 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)
Over / Under Voltage Protection Circuit for Boost DC/DC Output
No SCP time included (160ms from UVLO-off)www.DataSheet.co.kr
Applications
Power supply for the TFT-LCD panels used for LCD Monitors and Note Display
