Part Number: TIDA-01503 Other Parts Discussed in Thread: UCC28704 I don't have a normal output
1 waveform - primary side output (15V)
2 waveform - secondary side output (15V)
3 waveform - secondary side output (5V)
1. No load condition
2. Secondary…
Part Number: TIDA-01503
As I experiment, I have a question. When 400V DC is input to TIDA-01503, three outputs are available, 15V AUX, 5V iso and 15V iso. We experimented to verify three outputs one by one.
1. This waveform is input when 400V is inputted…
Part Number: TIDA-01503 Hello,
the schematic of TIDA-01503 Shows that the ISO 5V is supplied from higher turns Ratio than the ISO 15V; is that correct? On sheet 1 they are connected to suitable transformer Output positions; 15V up and 5V down. However…
Part Number: TIDA-01503 Other Parts Discussed in Thread: UCC28704 Hi
We would like to copy TIDA-01503 design for DC 96V ~ 150V in to generate two output rail 15V 0.6A and 5V 0.6A.
May I know how to modify TIDA-01503 design for this ?
Part Number: TIDA-00443 Other Parts Discussed in Thread: TIDA-01503 , Can I use TIDA-01503 board bias power to the TIDA-00443 ?
Is there any other better suggestion?
Hi PYTsai,
The closest reference design I am aware of is TIDA-01503. It will need to be modified slightly to meet your exact requirements. You can follow the design guide: http://www.ti.com/lit/ug/tidudd4a/tidudd4a.pdf .

hi
yes, Vp_AUX and Vs_Aux come from TIDA-01503.
The C2 connection is used to connect the output of TIDA-01501 to another TI design to transfer 12V to 5V and 3.3V. so you don't need these signals.

Part Number: UCC28700-Q1 Other Parts Discussed in Thread: UCC28704 , TIDA-01503 Hello,
We design a flyback power supply with primary side controller which uses the AUX winding of the transformer.
We have one question, is it possible to power primary side…
