Part Number: LM5123-Q1 Hello,
I have seen in the datasheet that initially, the LM5123-Q1 starts in forced DE mode and transitions to FPWM (if selected) by reducing the ZCD threshold from +4mV to -145mV.
What happens if, at this point, the sensed voltage…
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: 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 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…
Part Number: LM5123-Q1
Dear TI team,
we are currently having issues with a design that uses the LM5123.
We are using the LM5123 as a step-up converter, going from 10-32 V input voltage to 32 V output voltage. We originally had some issues with ringing…
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: LM5123EVM-BST Hi TI experts,
Question 1: Vgs turns hi already, but the Vds still kept hi, too. It makes me have poor efficiency and superheat. If TI experts can help me out with this, I will appreciate…
