Part Number: PMP21098 Tool/software: Hi,
PMP21098, 170W PC PSU Reference Design, 12V output.
The output will be raised from 0 to 12V after 6sec. i.e., It is taking start up time 6Sec. (Some times it takes less than 1sec)
But as per design it would…
Part Number: UCC28056 Other Parts Discussed in Thread: PMP21098 , UCC256304 , UCC24610
1.UCC28056 (PFC) and UCC25630(LLC DC/DC) are used in the schematic of the design PMP21098.
Now my idea is that: first the supply voltage of UCC28056 becomes Hi…
Part Number: UCC28C54 Other Parts Discussed in Thread: PMP21098
Hello
Out of WEBENCH I got a design for an AC/DC 240VAC --> 12VDC 7A converter. It uses the UCC28C54. It also uses a custom transformer with a "turn/ratio" of about 10 turns Np:Ns, 146…
Part Number: PMP22087 Other Parts Discussed in Thread: PMP21098 Tool/software: Hi,
Can you list alternative parts in PMP22087 design for 750317259 and 750317258 as they are not easily available. We can use a lower current capacity as well as my requirement…
Hello Suhas,
I would recommend starting from identifying the topology/ end application, efficiency spec, standby spec, etc. for your power supply.
One possible solution is UCC25640x LLC controller: below is the link to a 170W design for your reference…
Part Number: UCC256303 Other Parts Discussed in Thread: PMP21098 , Hi all,
I checked UCC25630x datasheet. But there is no word of "Latch".
OCP1 does not latch?
Could you get me a circuit example that is completely latched off by OCP1?
You know…
Hi, Ben
PFC and LCC both too need latch function(OVP,OCP)
and i reference PMP21098 it`s look like customer inquire.
if any suggestion, Please advise me.
Thanks,
Best regards,
Lawrence.
Hi Masazumi-san,
Thanks for your interest in UCC256302.
1. RVCC UVLO is not related to VCC voltage.
2. You may also pull the BLK pin below 2.13V to make the controller stop switching
3. VCC will slowly decay because the VCC capacitance is no longer…
