Good morning,
I have a problem with switching the voltage in priority mode.
I use below application.
Parameters:
VIN1 - 3.3V +-10%
VIN2 - 3V
VOUT current ~10mA (MCU and some digital ICs as load)
Scenario:
1. When I apply 3V to VIN2 from power supply I get the correct voltage of 3V on VOUT.
Channel 1 - VIN2, Channel 2 - VOUT
2. Then when I apply 3.3V to VIN1, VOUT droping to 2,6V and nextly vlotage is switched to VIN1 and I get 3,3V on VOUT.
Channel 1 - VIN1 , Channel 2 - VOUT
3. Nextly Im trying to switch back to power from VIN2 and here is problem.
When Im disconnecting 3,3V, IC does not switch correctly to supply the output from VIN2.
I can measure only 2.6V on output, and also this voltage is going back to VIN1 via IC and I have 2.6V on IN1.
In addition, I observed that if I short the lower resistor of the voltage divider in this condition, the output voltage returns to 3V.
Channel 1 - VIN1, Channel 2 - VOUT
What could be the reason for this behavior?
