TPS54380: Please tell me about the efficiency data and current limit of TPS54380.

Part Number: TPS54380

Hi, team.

My customers are considering using TPS54380.

※ Because this part is registered by customer, there is also a track record that we used from the past.

Then, please tell me the efficiency data (EFFI V SS IOUT) under the following conditions and the MIN / TYP value of the current limit.

※The efficiency data is wanted to see in the full load region.

VIN：5.0 V

VOUT①：1.5 V

VOUT②：1.2 V

Fsw：700 kHz

Best regards,

Pokkun（Masumi Sekiguchi）

    Pokkun,

    We only have efficiency data for Vout = 1.8 V with Vin = 3.3 V and Vin = 5 V. The minimum and typical values of the current limit are listed in the datasheet. 4 A min, 6.5 A typ for Vin = 3 V. 4.5 V min, 7.5 A typ for Vin = 6 V.
    If you are looking for the efficiency at currents above the rated current of 3 A, you can estimate it by linear extrapolation of the curves in the datasheet or EVM users guide. If you need for us to measure the data, can you give me a time line? I am currently occupied fully by a new project.
