5 Specifications

Note

Device Limitations (intended to be removed for final material):

1. Inductor current limit function is not optimized. TI don't recommend to use TPSM81033 at the

condition that the input current is higher than 5A. Final material is expected to improve the current

limit function.

2. TPSM81033 doesn't support to remove input voltage at heavy load. TI recommend to remove

input voltage at no load, or connect EN to GND first with load and then remove input voltage. Final

material is expected to support remove input voltage at heavy load.

(1)

Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply

functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions.

If used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully

functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.

All voltage values are with respect to network ground terminal.

(1)

JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with

less than 500-V HBM is possible with the necessary precautions. Pins listed as ±2000 V may actually have higher performance.

(2)

JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with

less than 250-V CDM is possible with the necessary precautions. Pins listed as ±500 V may actually have higher performance.
