Part Number: UCC28951-Q1 Other Parts Discussed in Thread: UCC28951 Tool/software: Dear Sir,
We are using UCC28951 for designing PSFB Board for 4kW Charger. The dead time(DT) is Non-Uniform and there is a difference in Dead Time(DT1) and dead time (DT2…
Part Number: UCC28951 Tool/software: Posting for a colleague:
Project Specs: Vout: 24VDC Vin: 550V P=500W I am using UCC28951 (PSFB topology) IC for DC-DC isolated power supply project. I have a full bridge synchronous rectifier on the low voltage (secondary…
Part Number: UCC28951 Tool/software: The connection of a resistor to the SS/EN pin cause an exponential relationship in the capacitor voltage (parallel resistor and capacitor with constant current source)
The voltage equation of the capacitor should…
But this model is also not having all the 24 pins. THis model will work only for specific application. I want the full unencrypted 24 pin UCC28951 IC. Please provide if it is feasible.
Part Number: UCC28951 Tool/software: What causes jitter in the PWM signal in the UCC28951, PSFB Converter?
At approx 20% load I am seeing the Duty Cycle vary/bounce between 2 points, approx 45% to 55% Duty
It results in audible noise. It is a negligible…
