Part Number: UCC28C53-Q1 Tool/software: Hi,
I built a simulation for Boost in Qspice using UCC28C53 and UCC28C53-Q1 PSpice Model ( SLUM838.ZIP).
Even when I ground the COMP pin I still observe some duty cycle in the controller's output.
It seems like…
Part Number: UCC28C53 Other Parts Discussed in Thread: UCC28C55 Tool/software: Dear team,
My customer would like to use UCC28C53 for their application.
As we can see like below, UCC28C53 with 100% duty and UCC28C55 with 50% max duty.
My customer ask…
Part Number: UCC28C53-Q1 Tool/software: Hi Ti team,
In UCC28C53-Q1 the minimum operation VDD supply voltage is not specified. What is the minimum operating supply voltage with meeting all operating performance requirements..
I will be using UCC28C53…
Part Number: UCC28C53-Q1 Other Parts Discussed in Thread: UCC28C53 Tool/software: Hi Team,
Do you have any Calculation sheets or Design guides for choosing or designing the transformer?
For the design requirement,
I/P = 24V
O/P = 5A, 24V
Thanks,
Mu…

Part Number: UCC28C53-Q1 Dear Team,
I am designing the flyback the with Vin 67 to 180rms, and Vo 12V, 2A. I have gone thru the Webench schematic, observed that 18V zener connected across VDD pin for protecting the IC.
the D12 is VZ 18V @ IZT 7mA, now…

Part Number: UCC28C53 I am using UCC28C53 in my flyback design and am seeing spikes on the VREF pin when a load is applied.
This waveform is DC with a 2A load applied to the output:
It seems the VREF pin sees spikes above 7V when the MOSFET switches…
