DC/DC Converter
Double/Triple/Quadruple Boosting 95% Excellent Power Conversion Efficiency Built-in
Voltage Regulator DESCRIPTION
The SCI7654 is a highly efficient, but low power-consumption DC-to-DC converter based on the advanced
CMOS technologies. It can generate an output
voltage double/triple/quadruple times higher than the input (in negative direction) if 4/3/2 external
capacitors are attached. With a built-in
voltage regulator, the SCI7654 can provide a stable output by setting the DC/DC output to any
voltage via two external resistors. This is optimum to the LCD panel power supply as the stable output can have the negative temperature gradient required for an LCD panel.
FEATURES
