Hi Nagai-san,

The UCD3138 device has a bridgeless demo board available, www.ti.com/lit/an/slua713/slua713.pdf . But at this time TI does not have a totem-pole PFC demo available.

Regards

Peter

Peter-san,
Why does TI's PFC EVM has two inductors?
I had see in TI's document to one inductor PFC topology.
(www.ti.com/.../slyt650.pdf)

One power device maker published a PFC EVM.
(www.transphormusa.com/.../Totem-Pole-PFC_TDPS500E2C1_0.pdf)
It uses the TMS320 and one inductor PFC.

I think , if to use the UCD3138, should be able to design an one inductor PFC.

Our customers are hoping that the PFC-IC for totem-pole is sold.
Because, they don't want to modify the firmware for each model.

Thanks,
Nagai

Hi Nagai-san,

At present TI does not promote any totem-pole PFC IC solution. I will tell the HPCS product line about the customer interest in this area. Can you provide more details about the business opportunity by email?

My address is petermeaney@ti.com

Peter
