Part Number: UCC28951 The UCC28951 can be synchronised between 50kHz to 1MHz (that is clear). However, what does it mean by synchronization range (see below attachment from datasheet).
Does this mean if I select a nominal switching frequency of 200kHz…
Part Number: UCC28951 Hello,
Starting with the SLUUB02A evaluation kit, we wanted to design our own ACDC power module. This includes PFC, standby power, and DCDC power (made with the UCC28951). It's only the DCDC part that interests me for this question…
Part Number: UCC28951 Hi,
We had made PSFB with SR schematic for 924W PSU. Input is 400V DC and output is 28V@33A.
We want TI team to review our schematic and give the feedack . So please provide contact mail ID with details.
Best Regards,
