Part Number: UCC28780 I'm working on a new design with the UCC28780. Startup is going through the normal sequence until it gets to the step where the RUN pin is supposed to go high. Run doesn't go high and PWML never goes high. VDD continues to drop until…
Part Number: UCC28780 I know the datasheet recommends a depletion type fet for the initial charging of the chip through the sw pin. But the depletion type FET's available to us in the high voltage packages are quite limited or straight up too big for…

Part Number: UCC28780 Tool/software: Helo:
We are going to use this chip for converting 30V to 100V for a 200W converter.
Isolated.
What other flyback chips can you suggest?
Also: what chip will give us a feeback loop of high bandwidth so that…
Part Number: UCC28780 Other Parts Discussed in Thread: PMP31092 Hi,

Part Number: UCC28780 Hello E2E Experts,
Good day.
I am developing a DC-DC on a UCC28780 chip with the following parameters: input voltage 18-36 V, efficiency 92%, frequency 200kHz, output voltage 5 V, output current 20 A, converter power 100 W, the…
Part Number: UCC28780 Tool/software: Hi team,
We are looking for a power chip recommendation. The requirements are as follows. Please recommend a suitable device.
1. This IC is used for flyback power supply control and can directly drive SiC tubes…
Part Number: UCC28780 Tool/software: Hello, I am currently working on designing a boost converter with a high step-up ratio. I need an efficient and compact converter, so the active clamp topology caught my attention. I'm looking into the UCC28780 as…
