SCI7654M0A/C0A
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
An input voltage can be boosted double/triple/quadruple to negative potential.
Input voltages: –2.4 to –5.5V (quadruple boosting), –2.4 to –7.3V (triple boosting), –2.4 to –11.0V (double
boosting)
Excellent vol tage conversion efficiency: 95% (Typ.)
Large output current: 20 mA (Max.) during quadruple boosting
Built-in voltage regulator (for stable voltage output)
Built-in reference voltage source for accurate regulation: –1.5 ±0.05V (CT0)
Regulator output voltage temperature gradient function: –0.04, –0.15, –0.35, –0.55%/˚C
Low current consumption: 130 µA (Typ.)
Low standby current: 5.0 µA (Max.)
Built-in oscillator circuit
5/6-time voltage boosting in negative potential by serial connection
