Part Number:DRV8302
1) I am using DRV8302 IC for buck as well motor driver. Designed output voltage is 5VDC. As the buck converter is independent from motor driver section, hence provided supply voltage to only 53&54 pin. (input voltgae 24VDC).
2) The Output was as per design and the voltage at VSENSE pin was 0.8V.
3) Now as i provided the same supply voltage to pin no. 29 ( 24VDC ), the output of buck converter changes from 5V to 8.5V. and voltage at VSENSE pin becomes 1.34 V. ???
4) again to get the desired output voltage the lower resistor of divider circuit need to increase ,by adjusting we achieve required voltage , but the resistor value and the Voltage at VSENSE pin are not as per provided in datasheet
Please help in above problem..
