Part Number: LM5155 Tool/software: Hello,
I want to design a circuit using this LM5155 which will get power from Lithium Battery but as the minimum input voltage is only 3.5V so requesting you to provide part which can support minimum 2.5V input and…
Part Number: LM5155 Tool/software: Hi,
I am using LM5155 driver for isolated flyback transformer. In reference designs optocoupler is recommended for isolated feedback. But we have a requirement of system lifetime 15years. As photocoupler has less lifetime…
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-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 The datasheet of this part says:
It can operate with the input supply voltage as low as 1.5 V if the BIAS pin is greater than 3.5 V.
In the schematic, i can see BIAS. But i can't see "input". Where is input?
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: 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: 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…
