Part Number: UCC28740 Hello TI Team,
I am currently working on an isolated flyback SMPS design and I am experiencing an issue with improper PWM generation from the controller. I would appreciate your guidance in resolving this problem.
Design Overview…
Part Number: UCC28740 Tool/software: Hello sir.
I am currently using the UCC28740 chip to make a flyback switch power supply load, which is a 24V 0.33A fan. Recently, I found that three consecutive UCC28740 chips are not working. After powering on,…
Part Number: UCC28740-Q1 Other Parts Discussed in Thread: UCC28740 Hi team,
My customer uses UCC28740-Q1 and they want to enable and disable this circuit with a MCU GPIO(like EN pin on other device). However, UCC28740-Q1 has no EN pin.
Question: …
