DRV2700EVM-HV500 High Voltage Piezo Driver Evaluation
The DRV2700 is a single chip high-voltage driver with an integrated 105-V boost switch, integrated power
diode, and integrated fully differential amplifier. This evaluation kit utilizes this high-voltage switch into a
flyback configuration that is able to achieve (but is not limited to) up to 500 V:
•
Controllable input modes: Analog input, PWM and MSP430 controllable
•
Variable output voltages from 0 V to 500 V
•
2 power supply inputs to isolate power consumption on DRV2700 application circuitry
•
4 convenient max output voltage settings
•
Small footprint (14 mm x 14.5 mm)
The evaluation kit is designed for all-around use and can be used not only for evaluation but can also be
used for prototyping into systems for driving piezo actuators, polymers, valves and many other
applications. The EVM also contains a microcontroller, LDO (3.3 V) and LEDs for status and input
settings.

EVM. To power the board, connect the DRV2700EVM-HV500 to an available USB port on your computer using a mini-B USB cable. The default board settings cause the microcontroller (MSP430) to control the inputs of the DRV2700 at power up. The MSP430 has each of these control settings low which disables the DRV2700, by default. -

Page 19: Input Filter
Input Filter The DRV2700EVM-HV500 has an active low-pass input filter to attenuate high frequency PWM signals coming from the input source. Depending on the input frequency and input voltage, the filter can be adapted to attenuate any undesired out-of-band content. This section describes the input filter requirements and the various respective configurations. -
