Part Number: TPS2121 I have a 5V input and a 3.7-4.2V input
Using the Highest Voltage Operation mode, the start-up is not consistent.
Using the 23.7K and 5K for the 5V on IN1 what will the recommended resistor values be for the 3.7-4.2V on IN2 be?
Hi Kalin,
We appreciated your great support!
1.The fast switch is only available when the both input are existing ,right?
I means the PR1 pin and CP2 pin that are only work when we have both input .
If we only have one input, the TPS2121 will auto select…
