Q: TPS61028 : Efficiency vs Current by 569213

Hi;

 

Our customer inquiries the Efficiency vs Current data of TPS61028 like Figure 3.

We appreciate to get the efficiency data at Vo=3.3V, if possible Vin~1.5V.

The efficiency data is the same for all TPS6102x devices, though the maximum obtainable output current will be different for each.  Figure 3 also applied for the TPS61028.  Efficiency will be slightly lower at 1.5V compared to 1.8V.

If more data is needed, it should be taken on the EVM with the customer's chosen inductor as this will affect the efficiency also.
