Part Number: LM25184EVM-S12 Other Parts Discussed in Thread: SN6507 , UCC256403 , , SN6501 , LM25184 Tool/software: Hi,
we need a TI proper solution for an isolated switching power supply, with: high efficiency (>80 %), small footprint, few components…
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…
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…
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 John,
Thanks for reaching out. I am assuming isolated DC/DC solution based on SN6501 to be supporting 5V @ 200mA to be meet 1W requirement. BAT54C has a absolute maximum forward current rating of 200mA and there is absolutely no margin. Hence, BAT54C…
Part Number: LMG3410-HB-EVM Other Parts Discussed in Thread: SN6505A , , SN6505B , TIDM-1007 , SN6501 , SN6505D-Q1
Due to supply limitations, I can only get SN6505A's instead of SN6505BDBVR's . It has a slower switching frequency than the B. This if…
Hi Antoine, Thank you for following up. Efficiency curves of SN6505 devices with 3.3V to 3.3V, 5V to 5V, and 3.3V to 5V transformers are included in the Typical Characteristics section of their datasheets. Below are a few examples: 5V to 5V 3.3V to 5V…
Part Number: SN6501 Other Parts Discussed in Thread: SN6505B Hi team,
My customer wants to use the SN6501 to design 3.3v input, 6.6v output, then use a LDO to generate 5v, 200ma.
we have found some transformers as the attachments. Could you please…
Part Number: ISO3086T Other Parts Discussed in Thread: SN6501 , SN6505B , SN6505A Hello,
Many EVMs and application notes mention Coilcraft transformer for use with ISO3086T. However, the coilcraft part is costly and hard for sourcing. Can you please…
Part Number: SN6501 Other Parts Discussed in Thread: SN6505A Hi Team,
My customer is surveying SN6501 and want to know if it can support 2 isolated output (Vout_1 and out_1 and Vout_2 are isolated). For his application, Vin is 5V, Vout_1 is 5V@100mA…
