Part Number: TPS62143 Hello,
I am using the fixed 5V output TPS62143 switching regulator in my design. It looks like I have a problem with overshoot on my input when power is applied. Is there a filter design TI suggests to suppress the overshoot on power…
Other Parts Discussed in Thread: TPS62143 Hi,
I have a question concerning the TPS62143 DEF pin. The datasheet states in a note that pulling the DEF pin high will provide a 5% higher output voltage. Is this a valid and stable mode of operation that can…
There are similar E2E posts concerning the inductor value, most seem to indicate a higher value solves the problem, such as: https://e2e.ti.com/support/power_management/non-isolated_dcdc/f/196/p/290682/1013706#1013706

Other Parts Discussed in Thread: TPS62143 Hi Community.
I have soldered schematic with the TPS62143 as Voltageregulator. I selected the components according to the WebBench Design Report. The partnumbers are not the same because my distributor did not…
Other Parts Discussed in Thread: TPS62143 Hi,
I've got a design that uses the TPS62143 in a standard 5V configuration - straight off the Web Bench and using the generated BOM values.
My problem is this is with the point of entry into power-save mode…
I create a board shield on Arduino mega 2560 witch takes 12v/15A as Input. It has some component like heater cartridge, fan, transistor. The arduino takes 5v from 12v with MC33269D-5.0, so not from TPS62143. The TPS62143 powered a "CubieBoard" wich need…
Other Parts Discussed in Thread: TPS62143 , TPS62140 The TPS62140 datasheet suggests that fixed output versions such as the TPS62143 only require 3 external components, but all given layouts indicate at least 5 components.
I assume CIN, COUT and L1 must…
It wasn't an error as such, but it didn't follow the EVM layout as closely as I'd first thought. If I remember correctly, some of the capacitors were connected with vias and not close enough to where they needed to be. The point was: I thought I had laid…
