Power Supply IC Series for TFT-LCD Panels
12V Input Multi-channel
System Power Supply IC
BD8160AEFV
No.09035EBT01
Description
The BD8160AEFV is a system power supply for the TFT-LCD panels used for liquid crystal TVs.
Incorporates two high-power FETs 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.
Features
1) Step-up and step-down DC/DC converter
2) Incorporates 2.6 A N-channel FET.
3) Incorporates positive/negative charge pumps.
4) Input voltage limit: 8 V to 18 V
5) Feedback voltage: 1.162 V ± 1%
6) Switching frequency: 500 kHz / 750kHz
7) Protection circuit: Under voltage lockout protection circuit
Thermal shutdown circuit
Overcurrent protection circuit
Short Circuit Protection
Overvoltage protection circuit for VS voltage (Boost DC/DC output)
8) HTSSOP-B28 Package
Applications
Power supply for the TFT-LCD panels used for LCD TVs
