Hi Kevin,
Normally this would be a two stage design, a PFC stage + a dc/dc isolation stage.
For the PFC stage we would recommend the UCC28180 CCM PFC controller,
For the DC/DC isolation stage you can look at the UCC28951 phase shifted full bridge…
Yes we are still determining the best topology and control IC. Would a simple fixed current limit be easier? What happens to TIDA-01501 when the load impedance is too low? Is it not feasible to implement a current limit or one that is controllable? I…
Part Number: UCC25600 Other Parts Discussed in Thread: UCC29950 Hello,
While looking at the tool "sluc146,Rev 1.2 2009-04-29", the Peak_Gain(m) versus Qe plot in sluc146 is not the same as in SLUP263.
The plot in SLUP263, TIDA-01501 and TIDA-01557…
Hi Bo Xian Yeh,
TIDA-01557 is a PFC + LLC design without auxiliary: www.ti.com/.../TIDA-01557
PMP20795 is a LLC design without auxiliary supply (please note that this design is LLC only): www.ti.com/.../tidrsc3.pdf
TIDA-01494 and TIDA-01501 both…

Part Number: UCC256301 Other Parts Discussed in Thread: UCC29950 , Hi Sirs,
we have two 450W and 750W PSU project.
And we do reference TIDA-01501 for 450W project.
could this same chips solution apply to 750W?
or I saw UCC29950 can output 750W…
Dear Ben Lough,
thank you for your fast reply.
These are really nice features ...
But I am still confused about gate drivers. You mention low and medium power designs (do you consider about 500 W of the reference designs, TIDA-01501 or TIDA-01494…
