Part Number: TPS40090 Other Parts Discussed in Thread: TPS43060 , LM5175-Q1 , LM5122 , LM5175 Tool/software: WEBENCH® Design Tools Does anyone have experience with the TPS40090 as a Boost Controller. I am impressed with the PMP2445 documentation and would…
Hi Kotaro-san,
There are many USB PD reference designs on LM5175 and LM5175-Q1 product folders. Please take a look at those and see if they fit your need.

Hi Zhao,
We apologize for holding you for long.
Here are the designs which can be used for your automotive application listed below.
Buck: 9~60Vin/ 5V~15A out. in 24V vehicle system: ti recommends to use LM5119-Q1

Hi Rohit,
Since this is no longer a Spice/bode plot problem it will be good to generate another thread describing in some detail the behavior of the converter when it does not work.
We have some material on LM5175-Q1 site on PCB design. Please also…
Hi John,
Sorry for the delay in responding to your question. The design parameters you provided are for a very high power load (from the perspective of the LM3488 in SEPIC configuration). The message indicating that a suitable FET cannot be found indicates…
Hi Vijay,
Thanks for the reply.
I have another question. If the control bandwidth is low due to the boost mode RHP zero, the capacitor in the compensation network can become big. Since C0G/NP0 are the best ceramic capacitors (Class 1) and they are…
John,
We are looking at the LM5175 (-Q1?) to provide a steady 12V output from a declining (voltage) bank of Super Caps (S/C) . The S/C will typically be sat @ 11.8V DC, and when the power source is removed the DC will decline (we are looking to run…
Part Number: LM5175 Other Parts Discussed in Thread: LM5176 , LM5177 Hi.
I want to use LM5175 in boost mode.
The H/W configuration environment is as follow.
- Input Power: 12-16.5V (Battery Power), (12V*6A)*(4 Battery Pack Parallel) = 288W

Part Number: LM5085-Q1 Other Parts Discussed in Thread: LM5085 , LM5175 Tool/software: I want to use the LM5085 in the to genrate the 7.5V, 5A.
But VIN is 4.5V -36V, so I have the question, when the VIN is less than the VOUT, maybe VIN is 4.5V to 7…
Hi Malakondareddy,
Are you on contact with a TI FAE for this application?
For the non-inverting buck-boost, take a look at the LM5175/6/7 family. And for 24V to 5V/8A buck stage, see the LM61480-Q1 8A converter.
