Part Number: UCC24636 Other Parts Discussed in Thread: UCC28740 , TL431 Dear officer,
I am writing to ask one question about a UCC24636 application in a flyback convert. When I plug in 80-160VDC in, 120V 1A out into WEBENCH, it provides me this circuit…
Part Number: UCC24636 Hi Sir：
I use the ucc24636 as auxiliary power controller, Vout =12V.. And I use the excel UCC24636-Calc to set the external resistance. I have a resistor Q1 in parallel and Q1 is 1200V MOSFET. it Out of work,The Vout i can get 12V…
Part Number: UCC24636 Other Parts Discussed in Thread: UCC24624 Dear Team,
our customer uses the UCC24636 for an industrial battery charger. The first version had an output voltage of 11-15.6V, so no problem.
In another project they are looking for a SR…
