Part Number: UCC3805 Other Parts Discussed in Thread: UCC2805 , UCC2803 , UCC2802 , UCC2801 , UCC2804 Hi,
I'm using the UCC3805 controller in a flyback design, converting 8V to 500V. The existing design has a 12k and 1.1nF on the RC but when measured the…
Part Number: UCC3805 Hi, Good day. Our customer is using the UCC3805 in their project and they noticed some change in the line regulation parameter. Kindly see the description below. ""The Datasheet Rev changed from SLUS270D to SLUS270G but you have not…
Hi David,
Results from QA group - The /81222 suffix was added for a specific application. It had 1 more test added to the normal ATE program.
You can sell these as standard UCC3805 parts. However, the /81222 parts were obsoleted in August of 2014, so…
Other Parts Discussed in Thread: UCC3805 Hi
Has anyone simulated a DC to DC converter (8V to 500V) by using the UCC3805 and a transformer for converting the lower voltage to the higher voltage. Actually I simulated the all parts of this structure except…
I very carefully replaced the UCC3813-5 one more time, observing all the precautions not to damage it. After a few minutes the REF pin went to 7vdc and the oscillator stopped.
I tried adding load resistors on the REF output to keep it from going above…
