Other Parts Discussed in Thread: LM5574 I'm using LM5574 to generate +/-9V from 50-55Vin. The same power input is shared with another SMPS circuit. The LM5574 output looks fine while another SMPS is disabled:
But when another SMPS is enabled a strange…
Other Parts Discussed in Thread: LM5574 , LM5116 Can the SYNC pins be directly tied together between the LM5574 and the LM5116 to synchronize them? I can set the LM5574 as the "master" (higher frequency).
Other Parts Discussed in Thread: LM5574 I'd like to test aux bias for LM5574 as suggested in datasheet SNVS478F on pg. 18 (see picture below). My question is why aux bias negative end is not connected to the ground but to the Vout? Let say that I have…
Other Parts Discussed in Thread: LM5574 Hello,
Is there soft start capacitance limitation for LM5574/5? If there is, please let me know the maximum capacitance value. Best Regards, Ryuji Asaka
Other Parts Discussed in Thread: LM5574 Hello,
Could you please let me know the sync pin connection of LM5574 when we don't use SYNC function?
Can we float this pin ?
Best Regards,
Ryuji
Other Parts Discussed in Thread: LM5574 Hello,
Can we use LM5574 by attached image circuit ?
Since Sync pin absolute maximum rating is 7V , I believe that this circuit is no problem.
If there are any concerning poit please let me know.
Best Regards, …
Other Parts Discussed in Thread: LM5574 , LM5017 Hello,
Need to design a +24V to -15V regulator capable of 20mA to 100mA output current.
Webench has suggested a design using the LM5574.
Can the LM5574 Eval Board be converted to generate a negative output…
Other Parts Discussed in Thread: LM5574 Hello All,
I have prototypes of a LM5574 design that has 7 - 41 V input and outputting 3.3 Volts. (I used WebBench to design it) It appears to be converting OK, but when I look at the recirculating diode side of the…
Dear Penny:
Thanks!
About your item 1=>Change LM5574 to LM5019.
We already design LM5574 in many other product.(54V to 3.3V).
Could you let me know your consider?
Thanks!
