Part Number:TPS2121
Hi Application tean,
We would like to know how to achieve fast switchover time(5us_typ) in Figure 23 application(manual switchover) on datasheet(SLVSEA3B).
In Figure.23 configuration, selecting VIN1 or VIN2 as input sourve voltage should be done by driving(toggling) CP2 by MCU.
But, there is the description that the CP2 voltage needs to be higher than VREF(1.06 TYP) to enable fast switchover time.
How must we drive CP2 pin from MCU to have fast switchover time?
(Does it mean that low input level of CP2 driven from MCU be higher than VREF?)
Best regards,
H.Someno
