104PW161 inverter for LCD (Liquid crystal display) modules is composed of a DC/AC inversion circuit, a luminance control circuit and a boosting transformer. The DC/AC inversion circuit inverts a direct current (DC) power supply into an altar current (AC) by the center-tap transmitter circuit that used transistors.
The luminance control circuit can control the luminance of cold cathode lamps for LCD backlight unit.
The boosting transformer is translated the low AC voltage that obtained from a DC/AC inversion circuit to the high AC voltage. Also the high AC voltage is outputted from a secondary side of the boosting transformer.
APPLICATIONS:
High AC voltage generator of cold cathode fluorescent lamp for LCD
FEATURES:
Pulse width modulation circuit
Alert circuit for malfunction
