Part Number: UCC28251 Is there a time domain/ transient model for this part? We wanted to run some simulations that may not be accurately reflected in the average model.
Thanks!
Part Number: UCC28251 Is it possible to design PWM full bridge with ZVS using idea from ssztd90.pdf?
UCC28251 outputs as follows:
Leg A: Controlled by OUTA (High-side) and SRA (Low-side). Leg B: Controlled by OUTB (High-side) and SRB (Low-side). …
Part Number: UCC28251 Hi Team,
The comparator voltage for COMP and SR_RAMP is 420mV in the Block Diagram. Is the COMP and RAMP/CS pin comparator also 420mV?
I saw a pretty old thread on the tolerance of this 420mV that wasn't answered. It may come…
Part Number: UCC28251 Tool/software: The RT Min Resistor is not as data sheet recommended
In my board it is 16k and not as spec 12.5K
I wont to set oscillator to 1Mhz in spec i can max 1.4Mhz
and it is limit to 800kHz in my board. If i set external…
Part Number: UCC28251 Tool/software: Hello,
The datasheet provides 2 different diagrams for COMP pin connection.
We are using this IC for Full bridge application, Primary control and peak current mode.
Should i combine both of the below circuit…

Part Number: UCC28251 Dear team,
We are using UCC28251 for isolated High voltage DCDC converter with voltage mode control. Now we are planning to use the device in current mode control.,
for voltage mode control, we have connected the ILIM pin to…
Part Number: UCC28251 Tool/software: Hi team,
This is FAE Jayden, continuing from the previous E2E thread, how long does it take for the device to enter the latch state and exit the latch state after the input voltage is undervoltage? Customers need…
Part Number: UCC28251 Tool/software: The datasheet describes how to "enter" pulse-enable operation by sending a falling edge to EN pin prior to SS reaching 0.3V. Great. As the other posts imply there are concerns with 'accidental' glitches causing the…
