Part Number: UCC38C45 Other Parts Discussed in Thread: UC3845 , Hi team,
When using UC3845 to test Flyback before, when the secondary output of Flyback is short-circuited, the Duty can be reduced, the Vcc pin voltage can be reduced, and UVLO can be triggered…
Other Parts Discussed in Thread: UCC38C45 , UCC28C45 Hello,
I have designed a flyback power supply to work from 20V to 190V using UCC38C45 and my design has completed.
I the data sheet i have seen that it can work only from 0 to 70 degree centigrade.but…
Hello Raju,
I reviewed the e2e chain/inquiries about your design using the UCC38C45 and the LT 1245 simulation. Your input range is 20-190VDC with a 5V output for the UCC28C42. I found a schematic for a L6562 in this e2e string which is a transition mode…
Other Parts Discussed in Thread: UCC38C45 , UCC28C44 , UCC28C45 Hi everyone, I'm working on a 15W flyback transformer based on the ucc38c45 ( Input 24Vac/dc - output 15V, 1A max ). At present I'm looking for information, application note, which help me…
Other Parts Discussed in Thread: UC1845 , UCC38C45 Hi
I am working in a flyback PS running on DCM using UC1845 or UCC38C45 the compensation is done by directly modulating the comp pin source current FB pin is at 0V.
What is the slope of the linear part…
Other Parts Discussed in Thread: UCC28C41 , UCC28C45 , UCC38C41 , UCC38C45 hi Team:
I want to designed a Isolate dc-dc power!
Vin: 10-16V
Vout:+12V/1A,-12V/0/5A;
product Size: 30*30*12mm can OK? if not,Product size can be increased;
Do you have any recommendations…
Other Parts Discussed in Thread: UC3845A , UCC38C45 , UCC38C42 I need to have a soft start on my flback controller that utilizes the TI UC3845A. I see the newer BiCmos part UCC38C45 documentation (SLUA257)indicates an implementation with a PNP transistor…
Anand,
On th eassumption that the 17 volts might drop I would recommend the UCC38C45
http://www.ti.com/lit/ds/symlink/ucc38c45.pdf
It is a flyback design and should be fairly simple to implement. With a 50% limitation on the duty cycle you should…
