Hi
The following schematic is to drive a mp5 micropump from servoflow. Does anything look alarming to you? all of the nets go back to a microcontroller
Thanks for taking a look!
Hello Mitch,
I looked over the schematic, my comments are below as seen in the image:
- For REXT (R10), please verify that the resistor value is consistent with the equation in section 9.2.1.2.4 Programing the Boost and Flyback Current-Limit, and your desired I(Lim)
-C13 is not labeled, refer to section 9.2.1.2.5 Boost Capacitor Selection, and note that the cap voltage ratings need to be considered.
-For your boost resistor network, I calculated VBST to be just over 77V based off of your resistor selection and equation on section 9.2.1.2.2 Programming The Boost Voltage. Please ensure that this is your desired output voltage before proceeding.
Overall everything looks good, just double check calculations and component selection. Let me know if you have any further questions.
Best Regards,
Javier Palomo
