Lcd backlight driving device with an isolating transformer

An LCD backlight driving device with isolating transformer, comprising:

• a DC power supply for outputting a DC signal to a square wave generator;
• said square wave generator for converting said DC signal into an AC signal and outputting said AC signal to a primary side of said isolating transformer;
• said isolating transformer for receiving said AC signal from said square wave generator, and then outputting said AC signal, from a secondary side of said isolating transformer, to a primary side of a driver transformer;
• and
• said driver transformer for boosting said AC signal inputted from said isolating transformer, and then outputting a boosted AC signal, from a secondary side of said driver transformer, to a lamp.
