UCC25800-Q1: UCC25800 vs bootstrap diode power supply

Part Number: UCC25800-Q1
Other Parts Discussed in Thread: UCC25800

Hi Expert,

I'm promoting UCC25800 to customer in GaN based laser power project. However, customer think bootstrap diode power supply can has lower EMI effect than UCC25800. Do you think is this statement reasonable? Can you list some advantages of UCC25800 vs bootstrap diode? Thanks!



  • Hi Jiandong

     We don't compare the bootstrap circuit and UCC25800 solution before. As a thumb of rule, due to the diode reverse recover, there is a larger dv/dt coupled to bias supply for GaN. Also I will send an email to US team and discuss with them to confirm that what's the cons and pons compared to bootstrap circuit solution.
