Hi Expert,

Does the below data is right? Vin=2.3V, Vout=5V@1A

Pout=5W, Pin around=5/0.72=6.95W, the input current will over 3A, But TPS61252 current limit maximum is 1.5A only.

thanks for pointing it out.
you are right. this device can't support 5W output from VIN=2.3V. i believe the VOUT is out of regulation at this high output current
