Hi Stanley,
For PMP30446 calculations I simply used Power Stage Designer tool (you can download it on TI.com) and select a Buck converter with an inductance that keeps it running in transition mode (boundary mode between DCM and CCM). I addition, this…
Part Number: PMP30446 TI PMP30446 reference design is 780V to 390V 1.5A DC/DC 585W buck converter. We have an application with the same input range (3 phase 480VAC, which is 680VDC after rectifying), but we need 90V 6A min. at the output. In fact, output…
UCC28C56H can be used but I think the power is quite high for a non-isolated, single switch topology but with enough heatsink/cooling, it is possible? You can download and use TI Power Stage Designer to check the voltage/current to compare possible power…
Hi Steve,
thank you for your great help. Thanks also to Danilo that he repost my inquiry to the E2E forum.
Do I understand correctly when I use the UCC28501 PWM controller together with UCC21220AD isolated driver the controlling of my non sync buck converter…
