Part Number: TPS2640 Hello, I would like to externally adjust the current limit set of the TPS2640. Digipots do not offer the range to cover the full current limiting ranges I would like to apply (0.1-1amp, Rlim=120k-12kohm) Is it possible to input a…
Part Number: TPS2640 Hi team,
Could you help review the TPS2640 schematic and layout? thanks
UV and OV disable or default setting.

Could you share your mail and send you the layout file? thanks
Part Number: TPS2640 Hello,
When driving a buck regulator, what would be an appropriate level to set the current limit at? I presume the regulator could draw large spikes of current at times that would be above the steady-state DC current. I'm thinking…
Part Number: TPS2640 Hello,
I am working on a design that will use the TPS26400PWPR and TPS259472LRPW eFuses. I have noticed in general that ICs have an absolute max requirement of -0.3V on various pins relative to ground. Typically, at what voltage…
Part Number: TPS2640 Hi,
I've got two questions regarding TPS2640 eFUSE. I noticed some discrepancies between the documentation for the IC and the evaluation board, hence the questions.
1. In the diagram of the evaluation board, a TVS diode (D8) is…
Part Number: TPS2640 We have added the IC in many of our PCBs. Now we have started testing the PCBs. but to my surprise none of the protection IC from any PCB gives any output voltage. We had to bypass the IC to power our PCBs. I am attaching schematic…
Part Number: TPS2640 Hi,
My customer only supplies 24V on OUT pin of TPS2640 under system test condition. Other pins (including IN pin) are no power supply as follows. On this case, what is occurred? Is TPS2640 is damaged? Please advise us.
I hope…
