●Description
The BD8163EFV is a system power supply IC for TFT panels. A 1-chip IC providing a total of four voltages required for TFT
panels, i.e., logic voltage, sauce voltage, gate high-level, and gate low-level voltage, thus constructing a TFT panel power
supply with minimal components required.
●Features
1) Operates in an operating voltage range as low as 2.1 V to 6. 0 V.
2) Incorporates a step-up DC/DC converter.
3) Incorporates a 2.5 V regulator.
4) Incorporates positive and negative-side charge pumps.
5) Switching frequency of 1100 kHz
6) DC/DC converter feedback voltage of 1.24 V ± 1%
7) Incorporates a gate shading function
8) Under-voltage lockout protection circuit
9) Thermal shutdown circuit
10) Overcurrent protection circuit
11) HTSSOP-B24 package
●Applications
Liquid crystal TV, PC monitor, and TFT-LCD panel
●Absolute maximum ratings (Ta = 25℃)
