TPS92641EVM: How to modify the schematics for 12A output?

Hi PY,

May I understand what the input voltage is?

The datasheet should give you enough information on how to design the TPS92641. I can help review the schematics if needed.

Best Regards,

Steven

Hi Steven,

can you provide more information regarding what should we modify on EVM schematics and which section of the datasheet should we refer to ?

Hi PY,

Section 8.2 Typical Applications from the datasheet provides a detailed design procedure for TPS92641.

Best Regards,

Steven

Vin= 24V~32V

Hi Vincent,

TPS92641 works for this condition.

Hi Steven,

Customer RnD concern the current accuracy.

If RnD reference TIDA-080008 reference design, is the current accuracy able to be under 12mA?

Do you have any suggestion to improve the current accuracy?

Best regards,

Hi David,

To reach <12mA current accuracy with a 12A max output, I think customer needs to do calibration for each device.

Section 7.3.4 Analog Dimming and True-Zero Operation from the datasheet provides a method to improve current accuracy, especially in low brightness condition.
