Hi,
I'm trying to implement the TPS62125 Enable Threshold and Hysteresis settings (EN and EN_hys pins). The datasheet Application section is clear about how resistors R_EN1 and R_EN2 affect the enable thresholds. However, there's very little information about how resistance at R_EN_HYS changes the hysteresis.
With a nominal VIN=12V and VOUT=5V, I chose these values:
VIN_startup = 10V
VIN_stop = 9V
R_EN1 = 1.1Mohm
R_EN2 = 147kohm
R_EN_HYS = 14.7kohm
How do I calculate the hysteresis in my design?
Thanks,
Michael
