Part Number: PMP21781 Other Parts Discussed in Thread: LM5155 , Tool/software: i understand that reference design pcbs are not for sale, but My customer is interested in evaluating the LM5155 and the circuit on the EVM wont work but the PMP21781 is very…
Part Number: PMP21781 Other Parts Discussed in Thread: LM5155 , LM51551 Tool/software: Hi, I hope you are doing well,
I have a question regarding an application using the LM5155x in a similar configuration to the PMP21781 reference design.
Specifications…
Part Number: PMP21781 Other Parts Discussed in Thread: LM5155 Tool/software: Hi! I am trying to design 30V to 150V DC-DC boost converter and I found "www.ti.com/.../PMP21781" reference design for that. But I see that it supports around 85mA current but…
Part Number: PMP21781 Hi expert,
Our customer has a 150V application and they refer to our PMP21781 reference design.
They found the Cx1 in the schematic is not the same with our general use, and the C11 is also DNP.
What is Cx1 here used for and…
Do you have any recommendations for a DC-DC converter capable of boosting from 12 V to 150 V with a constant output current of 60 mA, suitable for a supercapacitor charging application?.
Additional note: I found your18V-to-150V DC-DC converter solution…
Hi Aditya,
Please also help with the output current needed. Adding a ref. design with LM5155 device - https://www.ti.com/tool/PMP21629 and https://www.ti.com/tool/PMP21781
Best regards,

Hi Biswajit,
Thanks for using the e2e forum.
Your approach is feasible. I do not understand why webench does not allow a VOUT of 150V. As the VOUT at an asynchronous boost does not violate any abs max pin limits, there should be no problem. For part…
Hi David,
Thanks for reaching out with your question and for considering TI as part of your design solution.
First, is isolation required for this design? I ask as the maximum output voltage is around 200V. This will dictate the best solution for…
Part Number: LM5155 Other Parts Discussed in Thread: TIDA-020013 , PMP21781 I have a need for an adjustable boost converter that can output up to 150V at 0.100 mA. The input voltage would be off a 14.4V nominal lithium ion pack. Ideally this rail would…
