Hello Max,
Thank you for your interest in the LM5023 quasi-resonant (QR) flyback controller.
The LM5023 is specifically designed to operate only in QR and DCM modes. It is not possible to configure this controller into CCM operation.
I suggest that you…
Hi Behtan,
Yes, you can use voltage mode control with any current mode controller.
In order to accomplish this, you would need to apply 0.9V peak sawtooth waveform to the input of the current sense pin, which can be accomplished by using a fraction of…
Joginder,
UCC28C54-Q1 , is an automotive current mode PWM that is tailored for high-voltage (HV) HEV/EV and industrial applications. It is intended to be used in applications operating from ~1kV+ and TI has developed an EVM demonstrating it's used in a…
I revisited D/S of LM25037. For peak current mode control, LM25037 and UCC28C54 use different method actually. For PCM,
your original circuit maybe works, but I don't know what values are used originally on your board. This section in D/S provides details…
