Hi,

I'd like to know what max output current capability for ELVDD and ELVSS is on TPS65651A.

I did some calculation.

With 3V input, 4.6V output (ELVDD), F=1.6MHz, Eff= 80%, L=4.7uF

The current limit at 0.47A output current for worst case.

Is my calculation right?

Hello ,
First page of the datasheet mentions 300mA current capability on ELVDD/ELVSS rails.
Going with switch current limit of 800mA for ELVDD, 3V input, 4.6V output, 80% eff. L=4.7uH (3.76uH min with tolerance), switch should hit current limit at around 370mA.
Kind Regards,
Liaqat
