Description
The BD8166EFV 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-A N-channel FET.
3) Incorporates positive/negative charge pumps.
4) Incorporates a gate shading function.
5) Input voltage limit: 6 V to 18 V
6) Feedback voltage: 1.25 V ± 1.6%
7) Switching frequency: 500 kHz
8) Protection circuit: Undervoltage lockout protection circuit
    Thermal shutdown circuit
    Overcurrent protection circuit
    Short protection circuit of timer latch type
9) HTSSOP-B40 Package

Applications
    Power supply for the TFT-LCD panels used for LCD TVs
