Part Number: PMP10236 Hi Team,
Good day, one of our customer want to use PMP10236 as reference and want to know the reason why bulk capacitors for high bus voltage uses resistor such as 4.7Mega ohm in the design.
Thank you and looking forward…
Hi Aravind,
Depending on how tight your output voltage regulation is, you could do a flyback and have a winding on the transformer for each of your outputs. PMP10236 is an example of this.
Also take a look at the reference design database. You can…
Prajoth, hello and thanks for your interest in Texas Instruments and our TI Designs. We don't have an exact matching design, but please take a look at our PMP10236 TI Design, which features our UCC28722 flyback controller and let us know if this is close…
Hello John,
Thanks for your reply.
1. Transformer design details are -
Core EE10/5/5, N87 from EPCOS
Primary inductance ~4mH
Primary Turns N1= 280
Secondary S2/S2= 40/20
Bias winding = 40 Turns
2. It was nearly based on TI reference design…
