Part Number: LM5023 Other Parts Discussed in Thread: UCC28722 , UCC28C44 Tool/software: I want to design dc- dc flyback converter for below specs-
input voltage range= 14 to 150 Vdc
output voltage= 12Vdc
output current= 1.25amp
can i use LM5023 controller…
Part Number: LM5023 Tool/software: Dear Texas Instruments Support Team,
I am currently working on designing a DC-DC flyback converter with following specifications with LM5023:
Vin: 30-84V (DC input from battery)
Vout Isolated: (Multiple isolated transformer…
Hello,
You might want to study QR, Comp, CS and VDD with an oscilloscope to see what they look like to verify there is no noise on the QR pin. I would study before and after adding any capacitance.
If the noise is not present from the waveforms than…
Part Number: LM5023 Other Parts Discussed in Thread: TINA-TI Tool/software: Dear Texas Instruments Support Team,
I am currently working on a design using the LM5023 QR Converter IC, rated for 65W, 19V output, with a universal input supply. While simulating…
Part Number: LM5023 Other Parts Discussed in Thread: PMP41031 Tool/software: I was trying to design a multioutput flyback with Vin range : 100V to 700VDC and Vout : 18V, 5V, Pout : 65W (combined).
Is there a good reference material available to evaluate…
Part Number: LM5023
Tool/software: Webench Power Designer
Hi.
I recently made a 30V-145V to 24V DC/DC power converter. I used the output from Webench as reference and made small changes to the circuit for my design. I have tried both the Webench design…
Part Number: LM5023 Tool/software: 12V5A LM5023 B66229_87HE.pdf
The ripple in the circuit above is around 200 mvpp at 5 Ampere, without load 92 mvpp. Load regulation is very good, less than 0.5%. How do I reduce the ripple to at least 1% or 120 mvpp…
Part Number: LM5023 Tool/software: Hi,
I have SMPS project given the diagram below
Previously I had a ripple problem at the output which was solved by moving R23 to pins 1 and 2 of the opto guided by Ulrich...
However, I have a noise problem in which…
Part Number: LM5023 Other Parts Discussed in Thread: TL431 Tool/software: Hi,
I have SMPS project , where I have 6.5V @ 1.5A output as shown in the figure below:
However, the output with full load (around 1.3A) has this behavior as shown in the figure…
Part Number: LM5023
Tool/software:
Dear Team,
I am designing a DC-DC flyback converter using the LM5023 with an input voltage range of 15-150 VDC and an output of 12V at 2A. However, I am experiencing issues with the circuit.When supplying 15-60V, there…
