Part Number: PMP10098 Hi team,
Could you help?
I have a question about PMP10098 reference designs in this schmetic https://www.ti.com/lit/pdf/tidrdu9
The optocoupler TCMT1107 is used in the circiut but it is not available in any market in the world may…

I have a wide input design requirement, want to reference as PMP10098 DEMO board,
I have a question about power start-up, attach file is SCH
If input=19V,Q3 could not work, How the energy…
Part Number: PMP10098 Hello sir,
I want to use this design for my power requirement of a 12 volt and 0.400 ampere smps. Can you tell where i can found the transformer setail and aslo a reference circuit for my design .
thank you
Part Number: PMP10098 Dear sir
I recreate your ultra wide input design and works fine, but how to increase secondary voltage to 12 volt and 0.15 to 0.20 ampere. If any flyback design guide lines avaliable for the particulatur in which we can get required…
I could not find the transformer: 750370271 on the we-online.com Wurth web site. Is this the correct part?
Which would be the best way modify the reference design to deliver 1A @ 12V?
Thanks
Cheers
Dirk
Hi Giorgio,
It gets complicated to find the right solution since it is very system specific. I would say that it is better to look at reference designs to see how the compensation network is made and what techniques where used to eliminate the overshoot…
Other Parts Discussed in Thread: PMP10098 , LM3481 Hello,
I'd like to build a DCDC converter from +12Vdc to +15Vdc isolated with 30mA output capability.
I have seen the low power schematics PMP10098 but I'd like something which works with +12VDC input…
Yunus,
Can you give more details on your specification? I assume that the output must be isolated?
What is the output voltage and power level?
What is the tolerance on the 24 V ac input, i.e. what is the minimum value?
For sure, if a single design…
Jenny,
The input voltage range of 20-265 V ac is very wide and not so common.

Such a wide input range is challenging. Does the design need to be able to deliver full power 12 W even at min 19 Vdc input?
A DCM-only or variable freq valley-switching/QR controller will be challenged due to the very wide duty cycle range.
A fixed…
