Hello Team,
Input is correctly 1.2V. However When evaluating TPS65295, VTT has 0.9V regardless its expected voltage is 0.6V.
In this settings, VTTREF=Open.
When put capacitor on VTTREF, VTT has 0.6V.
Could you let me know appropriate pin settings when VTTREF is not used ?
Any advice will be appreciated.
Jin
Jin,
VTTREF can not be opened, used for internal reference, and the cap must be used always, which is used for VTTREF compensation.
