Part Number: PMP20612 Other Parts Discussed in Thread: TIDA-01464 Hello ! Why reference design PMP20612 and TIDA-01464 have such HUGE difference (about 2 times) in thermal map at 230Vac full load ? Schematic are the same, BOMs are identical.
BR, Grigo…
Part Number: PMP20612 I build high-end tube guitar amps in one of which, currently I use a combination of three Mean Well power supplies to get 450V @ 500mA, 6.3V at around 2.5A and a 12V in the order of around 250mA. I am looking to move on from that…
Hi Vikas,
In addition to what I suggested in my previous post, we can try a couple of things together you an try too to address this situation.
1. Tune the soft start time. Besides capacitor (Cvcomp_p)on VCOMP pin, there is other Resistor + Capacitor …
Hi,
PMP20345 uses primary side regulation (PSR) controller. Its control law allow the current sensing signal to be used to perform constant current control. Since it is difficult to change the current sense resistor to adjust the peak current level…
John,
All of the information and files for PMP20612 are located on the page.
I am not sure I understand what additional material you need?
thanks,

Hi Doi-san,
Yes, UCC28056 has brown-in but does not have brown-out. An external circuit would be required to implement a brownout function. An example can be found in PMP20612 reference design using LM8364: www.ti.com/.../tidrqy2.pdf . You can use this…
Part Number: UCC28180 Other Parts Discussed in Thread: PMP20612 , LM8364 Can anyone tell me if the addition of the diode across the inductor and boost diode would take care of the issue of no overcurrent protection?
I am experiencing the same issue that…

Hi Team,
My customer use LM8365 to impleasemt UCC28180 brown out function.
Find out UCC28180 not turn off gate PWM when AC power remove. (LM8365 output low). Looks D/S show only…
