TPS59632-Q1: Zero Load-line

Roy Zhang

Part Number: TPS59632-Q1
Other Parts Discussed in Thread: TPS59632Q1EVM-057

Hi TI Experts,

TPS59632-Q1 can support "zero slope load-line" as per the features description in its datasheet (SLUSDL4), could you please tell me how to implement it?

What I have got from TI website are the datasheet and TPS59632Q1EVM-057 (SLVUBR3), while they do not refer to anything about zero load-line implementation.

Thanks in advance,

Roy

TPS59632-Q1 can support Zero Load line operation. The resistor from DROOP to COMP sets the load line.

Referring to the EVM, this would be R29. You can open R29, and populate C17, R31 as compensation components.

Hi Matt,

Thanks for your clear guidance.

I looked into the datasheet and the EVM by your info, expecting to figure out calculating C17, R31 parameters when the design input conditions varying from that of the EVM, populating/de-populating C13, etc. in Zero LL situation.

As mentioned in the datasheet, a MS Excel-based component value calculation tool is available. Can you please shoot it to my for my better understanding of implementing the design with this part?

Thanks so much, Matt. I'd like to close this issue for now, and get back to you if, I had further questions after chewing these materials. :-)
