Other Parts Discussed in Thread: PMP8817 Hi,
we are building phone charger similar to PMP8817 reference design from TI.
Can you suggest any other transformer similar to Renco RLTI-1083 that would do the same job?
Consider that only problem that we have…

Hi James,
Yes, you can use the method of PMP8817 forTPS2523/TPS2561..etc..
There is only one winding in the secondary of transformer to output the power.
However, The total output power for PMP8817 is 20W. What you need is a 60W Power.
For the 60W power…
