Part Number: LM5123-Q1-DESIGNCALC Tool/software: Hi, in "LM5123 Boost Controller Design Tool" spreadsheet,
Ruvlo_bottom_calc doesn't seem to be catering for the 10uA hysteresis current.
e..g. with Vuvlo_on=21V, Vuvlo_off=18V, Ruvt 252k. It then shows…

You can also use the https://www.ti.com/tool/LM5123-Q1-DESIGNCALC Best Regards, Johann…
Hi Martin,
Thanks for using E2E.
Could you please share you schematic including your specs as well as the filled out excel calculator for your design?
This will make the review more efficient. https://www.ti.com/tool/LM5123-Q1-DESIGNCALC
Thanks…
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…
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…
Hello Phil,
May I please ask you first, to properly fill in your personal information (The system only shows questionmarks instead of your name). Can you please provide me with the following information: Vin min and Iout max / maximum output power.…
Part Number: LM5123-Q1 Hello, My customer would like to use C simulation about LM5123 to optimize their design. However, the Webench simulation says “simulation not enabled for this design”. Why simulation can not be used for LM5123? Best regards, K.…
Part Number: LM5123-Q1 Tool/software: Hi team, I am Mahmoud Alsheikh, Hardware Developer with paragon AG, Germany.
I try to design the lm5123-Q1 with following parameter:
Vin = 13V, Vout = tacking voltage from Audio single from 20V to 45V.
Power…
Part Number: LM5123-Q1 Dear Team,
My customer is designing the LM5123-Q1 application circuit. About UVLO setting, when they designed the external UVLO resistor voltage divider (RUVLOT, RUVLOB) with reference to the application note, but it did not achieve…
Part Number: LM5123-Q1 Dear Team,
My customer is evaluating the LM5123-Q1, and is considering to improve the efficiency of the LM5123-Q1 application. Since they would like to redule the power loss of internal VCC Regulator, they consider to input the…
