Description: The Proportional Voltage Booster provides a simple means of obtaining the high DC voltage used for driving
piezoelectric devices statically. It requires only a low-voltage DC supply (or the output of an op-amp) on the input leg and a drain
resistor on the output leg.
The Voltage Booster is small, PCB mountable, and well suited for low current / high voltage applications. Output voltage
is proportional to input voltage, and is linear from ~10% to the maximum output voltage.
• Low output ripple,
• Floating output to enable the user to choose either positive or negative drive,
• Short circuit protection,
• Reverse polarity protection.

Output voltage as a function of Input voltage.
A 500K ohm discharge resistor across the output terminals is recommended
to sink charge when input voltage is removed.
