Hi Thangasamy,
Thank you for your patience. Yes, I did try to simulate the file you have shared and I did notice the same error while running transient analysis.
The issue is primarily due to the transformer. Since the transformer is a short for DC analysis…
Part Number: PMP4190 Other Parts Discussed in Thread: SN6501-MULXFMR-EVM , SN6505B Hi,
I have design SMPS using of PMP4190.
I/P-3 VDC to 6VDC
O/P-5V/400mA with 1500VDC isolation
I am structing Transformer. As per reference design I am not found transformer…
Part Number: SN6501-MULXFMR-EVM Other Parts Discussed in Thread: SN6501 , SN6505A Hi TI team,
I am in middle of developing a product using SN6501.
When I evaluate the part using SN6501- MULXFMR evaluation board, I've noticed the very poor efficiency in…
Hi Ethan,
Since the EVM for SN6501 has multiple designs (5 units and 5 transformers), the tests were done on an internal test PCB. This PCB is similar to the schematic in EVM and has no EMI filters or other components. Therefore, SN6501 passes the emissions…
Other Parts Discussed in Thread: SN6501-MULXFMR-EVM Hi team,
I have a customer that is requesting the Altium project files for SN6501-MULXFMR-EVM. Does someone have those to provide?
Thanks,
Billy
Other Parts Discussed in Thread: SN6501-MULXFMR-EVM , SN6501 Dear all,
Our customer is studying SN6501-MULXFMR-EVM now. I have gotten a question regarding SN6501-MULXFMR-EVM from the customer. So please teach me about it.
[Question] How much is temperature…
Hi Bright,
1. Yes.
2. Even so, you can use a flyback, but it will take up more room.
3. you need to use the SN6501 to drive the primary of a small transformer, and you rectify the secondary to get your 16V gate driver supply rail.
4. RT pin voltage looks…
Hi David,
Please consider first that Q5, C4, D4, R2 and Q4 are not used, therefore C3, R1 and Q3 are connected directly to J1 (24Vin) by means of R100 and R3, which are both 0 Ohm resistors. Vdd of the SN6501 is supplied by Q3, while Vcc is kept to D3…
Hello Chethan,
It is feasible to replace the combination of gate driver + pulse transformer with the UCC20225. A phase shift full bridge is suitable for such modification because most of the time all primary side MOSFETS are switching at 50% duty cycle…
Hi Ann, Thank you for posting to E2E! An example our customer may use of SN6501 with 200mW output is on the SN6501-MULXFMR-EVM. This EVM shows configurations for different input / output options and their small total solution size. Each channel on the…
