一,产品概述(General Description)      
   The JTMH3807 DC-DC converter supplies all three voltages required by small thin film transistor (TFT) liquid crystal
display (LCD) panels. The compact JTMH3807 uses a single inductor to generate independently regulated positive and
negative outputs.yQ3嘉泰姆

The main output, AVDD, is post-regulated to provide a low-ripple source drive voltage for the LCD display. The
auxiliary outputs generate a boosted output voltage, VGH, up to 20 V, and a negative output voltage, VGL,        low to -20 V
for the LCD gate drive. The device has internal over-current protection cycle by cycle and thermal shutdown for high reliability
during fault conditions.yQ3嘉泰姆

The JTMH3807 is available in a DFN-12L package.yQ3嘉泰姆
