Hi Sergi,
It is stated for a proper FPWM operation you would need this condition fulfilled, so it is possible that it would not enter the FPWM mode with these conditions not fulfilled, it is difficult to state what will happen exactly in this case, but…
Part Number: LM5123-Q1-DESIGNCALC Hi,
I ran into discrepancy between design calculator in Excel and Webench concerning values for COMP pin for LM5123 IC.
When I enter same input values in both cases, I get pretty much different values of resistor and…
Part Number: LM5123EVM-BST Other Parts Discussed in Thread: LM5123-Q1 Hi, Team
Hope you are doing well!
My customer used our LM5123-Q1 EVM to test the restart time after power off and found that the recovery time was too long.
Working condition: Vin = 11V…
Part Number: LM5123-Q1 I am using PSPICE for TI and want to test the LM5123-Q1 PN. I can't find the test circuit of the Transient model (I downloaded the latest version,rev.B). Is it available or is planned to be in the near future?
Thank you
Part Number: LM5123-Q1 The LM5123-Q1 datasheet says that to use the Programmable Spread Spectrum (Dither) feature connect a capacitor to the SYNC/DITHER/VH/CP pin which then works at about 1V. The datasheet also says that if you want the charge pump to…
Part Number: LM5152-Q1 Dear TI team,
can you tell me the difference between the LM5152 and the LM5123? Except for the implementation of the PGOOD / Boost Status pin, they seem identical.
Best regards

Part Number: LM5123-Q1 Other Parts Discussed in Thread: LM5121 , LM51551 Hi,
I've tried to design boost converter using LM51551 and LM5121 without success and decided to give LM5123 a try. I've used both Webench Power Designer and Power Stage Designer 5…
Part Number: LM5123-Q1 Hello,
While following the application note "How to Design a Boost Converter Using LM5123" (SNVA991, Oct. 2022) , I noticed a discrepancy in section 2.3: Current Sense Resistor Selection (page 5). The calculations show…
Part Number: LM5123-Q1-DESIGNCALC Hello!
I've encountered two differences between the design tool an the datasheet:
The datasheet mentions 470 p F for C_VREF (Section 8.3.7), the picture in the design tool states 470 n F.
Using an V_UVLO_ON of 8 V,…
Part Number: LM5123-Q1 Hello,
I'm working on a boost converter using the LM5123, and I've run into some discrepancies between the equations given in the App Note "How to Design a Boost Converter Using LM5123" and the equations used…
