Part Number: TIDA-01168

We have stability issues with our converter which is based on the TIDA-01168. What is the correlation between the coefficients used in the software (Buck mode shown below) and the LM5170 design calculator? What parameters were entered in the LM5170 calculator to obtain these coefficients?

/* Buck mode digital compensation constants */
#define B0_BUCK (2.602812)// (0.443017) /* B0 constant */
#define B1_BUCK (0.040566)//(0.264689) /* B1 constant */
#define B2_BUCK (-2.562246)// (-0.17832) /* B2 constant */
#define A1_BUCK (0.918233)// (0.466008) /* A1 constant */
#define A2_BUCK (0.081767)// (0.533991) /* A2 constant */
