This should meet 100ms PCIe bus enumeration timing requirement. If we have sufficient margin with TPS544C25’s default ~ 6ms SS time we will use this pin as TSNS for external temperature monitoring otherwise will load a 14.7K or 22.6K resistor at Cth instead…
Part Number: TPS544C25 Other Parts Discussed in Thread: TPS544C20 Hello,
My customer has a few questions about the TPS544C25 VOUT setting.
They want to use VOUT = 0.85V without PMBus control.
1. Output voltage by VSET
Are all of the following A and…
Part Number: TPS544C25 I am planning to generate 0.55V/30A current using TPS544C25.
Can I use only Resistor Configuration to set the 0.55V , or can the value be programmed only using EEPROM.
Part Number: TPS544C25 Hello,
We are having problems writing to and reading the value back from the SMBALERT_MASK. We are using the PMBUS SMBALERT_MASK Command as detailed in the PMBus Power System Mgt Protocol Specification – Part II – Revision 1.2 page…
Part Number: TPS544C20 Other Parts Discussed in Thread: TPS544C25 Hello,
My customer is considering designing a board that can use either the TPS544C20 or the TPS544C25 with only the BOM change.
Q1. TPS544C20 : BPEXT and TPS544C25 : VSET The function…
Part Number: TPS544C25 The datasheet shows the IOUT_OC_FAULT_LIMIT accuracy as +-10% when the output current is >= 20A, but does not indicate the accuracy for output currents less than 20A.
What is the accuracy on the IOUT_OC_FAULT_LIMIT threshold …

Double check to make sure the external components, including their parasitics such as ESR, ESL, and Capacitor Derating are the same in the WeBench and pSpice simulations. WeBench generally imports these parasitics automatically from it…
Part Number: TPS544C25 Other Parts Discussed in Thread: TPS546C23 , TPS543C20A , TPS543B20 Hi,
We have used TPS544C25 in our project for generating 1.2v @ 11A and 1.2v @ 7A.
We are getting 1.2v from both the regulators but power good signal from both the…
Part Number: TPS544C25 Hi
We are using the TPS544C25RVFT part number in our design and we are facing some issues in this IC regarding the PGOOD pin issues like when output is coming that time PGOOD pin is showing low but this is completely opposite of…
Part Number: TPS544C25 Other Parts Discussed in Thread: TPS544C26 Hi team,
Is there a latest datasheet of TPS544C26 that I can read to introduce to the customers
Please send it to fredcheng@ti.com
Thanks!
