Part Number: LM5155-Q1 Tool/software: Hi,
I want to use this LM5155-Q1 IC as a pre boost solution, but I am able to understand the functioning of the pin UVLO/SYNC/EN.
In my application, I want to use SYNC, EN & UVLO functionality all together.

Part Number: LM5155 Tool/software: Hello guys,
One of my customers is considering using LM5155 for their new products.
At this moment, they have the following questions. Could you please give me your reply?
Q. They calculated inductor value using…
Part Number: LM5155 Tool/software: I am building a boost circuit using LM5155, with an input of 24V and an output of 150V/500mA. When unloaded, the output is normal at 150V, but as the load increases to 3kohms, the output voltage begins to drop. When…
Part Number: LM5155 Tool/software: Niklas,
Problem solved!
As you had rightly suggested, I had to play with the compensation networks R and C values.
Initially, I thought I can make use of the bode plot in the spreadsheet simulator, but none of…
Part Number: LM5155 Tool/software: In my design, my LM 5155 is connected to a regulated 24V regulated supply. The load is an LED that needs 28~37 V, with less than 1 A of current. I need to control the brightness of the LED with a reference command voltage…
Part Number: LM5155 Tool/software: Hi E2E,
My customer has a new project to study as the following.
Product specifications: Input voltage range: 4.5~18, 9~36, 18~75 VDC
Therefore, the use of LM5155x requires emitter follower lines, and the size…
Part Number: LM5155 Tool/software: Hi Team
customer need double confirm, we reviewed the customer schematic according to the LM5155EVM-SEPIC User's Guide and it seems to be ok,
the customer is also to modify the feedback method.
please kindly let…
Part Number: LM5155 Tool/software: Webench was unable to provide BOM costs for the LM515X family of step-up controller for a 18 to 32VIN to 35Vout @1.5A desing..This is due to the relatively unimportant soft-start capacitor always coming up as a custom…
Part Number: LM5155 Tool/software: Dear TI Team,
Do you have any advice on how to eliminate this double switching pulse? These are measured waveforms using a custom board and BNC probe contacts: output voltage (yellow channel), switch node voltage …
