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-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 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…
Part Number: LM5123-Q1 Other Parts Discussed in Thread: TAS5825P Hi everyone,
we are using LM5123 in combination with the rail tracking amplifier TAS5825P. Generating the voltage for the tracking pin works well with some additional circuitry however we…
Part Number: LM5123-Q1 After start-up, voltage at UVLO/EN about 12V (I linked it to Vin, much higher than the UVLO threshold) but voltage here will keep drop till shut-down the device.
In datasheet, current sink internally should disable when voltage…
Part Number: LM5123-Q1 Other Parts Discussed in Thread: TIDA-020033 , , TAS6584-Q1 Hi experts,
My customer think about LM5123-Q1 + TAS6584-Q1 solution. (TIDA-020033)
At TAS6584, they are thinking 100Wx4ch=400W. Is it possible to boost in single phase?…
Hello Benedek,
Did you fill in the calculator for your 19V and 28V designs as asked by Niklas? Please attached the filled in files in this thread.
The above layout is not good for a power supply converter. So it is possible that the whole measurement…
Gentlemen,
We have not seen an update from you for three weeks, so I assume the questions are answered and the issue is solved. I close this thread now. If there is still something open, please reply and the thread will get opened again. If you have any…
Part Number: LM5123-Q1 Hi,
I have a question about why we need the offset voltage 0.3V between TRAMPS and PWM comparator? What's this voltage for?
Thanks!
