Part Number: UCC33420 I am looking at a low-noise application using the UCC33420. To reduce noise during a particularly noise-sensitive measurement duration I want to turn the regulators off. I have been noticing, what seems to be, switching coming from…
Part Number: UCC33420 I'd like to know about the Radiated Emission of Application Note "How to Pass CISPR32 Class B for UCC33420-Q1".The smallest margin is around the switching frequency of 64.5 MHz. What is the margin (dB) for the QP value at this frequency…
Part Number: UCC33420
Dear all,
We are using the UCC33420 in our application and have observed failures during IEC 61000-4-2 ESD testing .
Test conditions:
Standard: IEC 61000-4-2
ESD level: 8 kV air discharge
The ESD event is applied on…
Part Number: UCC33420-Q1 Hello,
What are the min, max, and typical delay times for rising and falling inputs on the EN/FLT pin? I am trying to time disabling the converter relative to some critical analog measurements.
Thank you.

Part Number: UCC33420 Hi team,
My customer has a new design with a UCC33420. However, the engineers found that they need an additional 470uF bulk capacitor to solve the transient load problem. Could you please comment on the maximum allowable output…
Part Number: UCC33420-Q1 Other Parts Discussed in Thread: UCC33420 Tool/software: Hello,
I downloaded the SIMPLIS model for UCC33420-Q1 from the TI product page and tried running it in the free trial of SIMPLIS . However, when I click Run , it shows…
Part Number: UCC33420 Tool/software: Hi team,
I wonder whether UCC33420 will decrease frequency when light load, and how low?
I didn't find description or characteristics figure in datasheet. Could you pls share me?
Thanks,
Severi
Part Number: UCC33420-Q1 Other Parts Discussed in Thread: UCC12050 Tool/software: Hello,
I am currently evaluating the UCC33420-Q1 for my design, but I noticed that a PSpice model is not available for this device. For simulation purposes, I would like…
Part Number: UCC33420 Tool/software: Hi! sir:
May I know is it possible to do filtering (CM/ DM filtering) at input/ output of UCC33420 to have the output noise lower than 100uVrms within 1Mhz BW.
Do we need to put Y-cap in between input GND and output…
