TPS61099: Max output current and the package information

Miatsu Okitsu

Part Number: TPS61099

Tool/software:

Dear,

Please let me ask 3 questions about the TPS61099.

1.) In the first page of the datasheet, there are 2 types of packages, WCSP and WSON. However, on page 23 and onward, there are different package, DSBGA and WSON. Is WCSP as same as DSBGA?

2.) What is the difference between TPS61099 and TPS61099x?

3.) What is the maximum output current when Vin=3.3V, Vout=5.5V?

Regards,

Miatsu

Hello Miatsu,

1. Yes, please see here the different package families TI is using: Find TI packages | Packaging | TI.com

2. The x at the end replaces the different numbers shown in the Device comparison table, see here: https://www.ti.com/document-viewer/TPS61099/datasheet#GUID-1CE2690F-FD36-4D5D-ACBF-D7DB36A5F3CB/TITLE-SLVSD88SLVSD888669 So the x stands for different fixed output voltage versions.

3. The output current capability will be in the range of 0.4A. But this is somewhat dependent on the cooling you are using and the ambient temperature you have.

Best regards,
Brigitte
