Hi Brian,
The TPSM365R6 device will only work with up to -13 V of output voltage in an IBB configuration. This is due to the non-IBB version only being able to output 13 V max.
However, the TPSM5601R5H should be able to support this IBB application at…
Part Number: LM5175 Other Parts Discussed in Thread: LM5176 , TPSM5601R5H Dear Support, my design (name: 56000080200) has this specification : Vin=20-30V, Vout=24V, Iout=20A, max ambient temperature 60°C (based on LM5175 or LM5176). Typical operating condition…
Hi Ridge, thank you for reaching out so fast.
By the way, the actual IC that we use has the PN TPSM5601R5HRDAR.
Here are the startup waveforms.
Yellow trace is the NMOS enable signal (3.3V level). The cyan trace is Vin. The 3.3V enable is trigged from…
Hello Ernst,
You may be able to improve the emissions with additional input filtering (e.g. LC filter on the input) and/or slowing down the switch rise time (e.g. R10 resistor on the evaluation board).
Here is an application note to help you design an…
Following your suggestion, I requested samples for the ISOW7840F, UCC12051-Q1 and TPSM5601R5H. This was the reply which is very frustrating. At least people working in TI should know these ICs are all out of stock...
On the TI store it is like this..…
Hi,
You maybe able to modify this EVM to -9V to meet your design.

Hi Harrison,
If you open the TPSM5601R5H test circuit in PSpice for TI, you will see this schematic:
This is what I tried and the reason I did not run into the problem is that this parameter is defined in the schematic (red box).
You can do the same for…
