Part Number: LM5170 Other Parts Discussed in Thread: PMP15035 Tool/software: HI Team
Customer need a solution using non-isolation controller to convert Vin 48V-84V to Vout=60V@25A.
If LM5170 can be used for this requirement?
Hi Jeffrey,
It is not possible to configure LM5171 this way.
You may configure LM5171 as two stage boost + buck for bi-directional buck-boost operation. Pleae refer to PMP15035 for more details.
You may consider LM5177 for 4-switch buck-boost.
Best Regards…
Hi Nikita,
The LM5171 or LM5170 cannot be used as 4 switch buck-boost. But it can achieve bi-directional buck-boost function with two stage: boost + buck.
You can find https://www.ti.com/tool/PMP15035 for this application.
Best Regards,
Feng Ji
Can I control the PMP15035, LM5170 with external digital circuit like Microcontroller.
I see PMP15035 board was not for sale mentioned in your website

Hi Rudra,
Thank you for reaching out and for considering our solution. Your are at the good start point by looking at a buck-boost controller. For the operating voltage range, the LM34936 can support. However, its integrated drivers are not strong enough…
Hi User,
From your description, what you need is a buck-boost circuit. To use the LM5170, you can refer to http://www.ti.com/tool/PMP15035 , using two stage to implement the buck-boost function. You can control CC and CV for the output stage. By controlling…
Other Parts Discussed in Thread: TL1451 , LM5118 , PMP15035 , LM5170 , LM5175 , LM5176 Hi,
As per our requirement, we need 12 V@12 A output, and 12 V @22 A output from the 8 to 46 V. The Peak current up-to 96 V. So please guide us for selecting the correct part…
Hi Salman,
Sorry, I should have typed PMP15035. Please see the link below

Based on your input above I think this might be the best solution for you. Please note that the MOSFETs, inductor and loop compensation will need to change…
Hi Lius,
Thank you for your interests. You should refer to the following reference. It is 12V to 12V but can be modified to do 24V to 24V. The power level can be scaled by increasing or reducing the power inductors and also the MOSFETs.

Hi Praveen,
Thank you for reaching out, and yes the LM5170 supports such applications.
The dual battery system refers to the automotive 48V and 12V dual battery system used in mild hybrid electric vehicles. Depending on your power architecture, you may…
