Hi Team,
Original question post: https://e2e.ti.com/support/motor-drivers/f/38/t/909339
Customer did the test. After reducing the ripple, he found that after inputting a constant PWM, the voltage of the capacitive load could not be stabilized within the value set by himself.The specific circuit is in the original post. Is there a problem in calculating the relationship between PWM and output voltage? What other parameters should be considered? (The formula is derived from several formulas in the manual)
Thanks,
Annie
