Description

1. OUTLINE

1.1 STRUCTURE AND PRINCIPLE

104PW191 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.

1.2 APPLICATIONS

· High AC voltage generator of cold cathode fluorescent lamp for LCD

1.3 FEATURES

· Pulse width modulation circuit

Note1: The power supply lines (VDDB and GNDB) occurs large ripple voltage while luminance control of LCD lamps.

There is the possibility that the ripple voltage produces acoustic noise and signal wave noise in audio circuit and so on.

Put a capacitor (5,000 to 6,000mF) between the power source lines (VDDB and GNDB) to reduce the noise,

if the noise occurred in the circuit.
