FEATURES

 Optimum one-connector, two-output design for thin liquid crystal panel displays.  This inverter carries a PMW(pulse modulation width) circuit, TDK’s unique circuit design. This allows dimming of lighting over a much wider range than is possible using conventional types of dimmer circuits. The type of dimmer control can be selected as desired, either voltage control(Vbr:0 to 1.6V) or resistance con- trol(VR:0 to 10kΩ).  Built-in overcurrent protection circuit increases safety.  Monitor brightness is always kept stable since the built-in current feedback illumination stabilization circuit compensates for inverter input voltage variation(±10%).  The board backside is free of wiring pattern. Cost reduction and simplified mounting are made possible by a design that only uses one side of the board.  Operational safety is increased by the use of two types of insula- tion for high voltage components.

APPLICATIONS

Various types of color liquid crystal displays, computer touch pan- els, controllers, medical devices, ATMs, POS terminals, telecom- munication terminals, microscope monitors, fishdetectors, ticket sales machines, amusement arcade machines.
