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
