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…
Part Number: UCC28251 Tool/software:
Hi Team,
This is FAE Jayden, my customer ZTE would like to know which pins of UCC28251 have latch-up effects? Is it just the VDD pin? Are there also latch-up effects on output pins such as OUTA and OUTB?
If so…
Part Number: UCC28251 Tool/software: Hi team,
This is FAE Jayden, ZTE is using UCC28251 in HSFB power module. During the application process, they found that the voltage of FB/EA- was -0.6V, which exceeded the requirement of -0.3V. Is there any application…
Part Number: UCC28251 Other Parts Discussed in Thread: OPA2388 Tool/software: Hi team,
This is FAE Jayden, ZTE is using UCC28251. They have raised one question that I need to check with you.
Can the overcurrent protection function of UCC28251 be made…
