Description
TMS91904CT is Inverter Transformer. An inverter transformer for LCD (Liquid Crystal Display) is a specific type of transformer used in the backlighting circuit of LCD monitors and LCD TVs. The backlighting system in an LCD panel requires a high voltage to power the Cold Cathode Fluorescent Lamps (CCFLs) or Light Emitting Diodes (LEDs) used to illuminate the screen from behind.
The main function of the inverter transformer is to step up the low voltage from the inverter circuit to a higher voltage necessary to light up the CCFLs or LEDs. The inverter circuit converts the DC voltage from the power supply into an AC voltage, which is then stepped up by the inverter transformer to provide the required voltage to drive the backlight.
