Piezo Systems: Proportional Voltage Booster

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.

Features:

• Low output ripple,
• Floating output to enable the user to choose either positive or negative drive,
• Short circuit protection,
• Reverse polarity protection.
