We are currently working on a SPEIC circuit, but there are issues with the design. We plan to replace D33 with an inductor. Could you recommend the inductance value? Should both the inductance and current rating be the same as L7? Currently, L7 is 2.2uH…
Part Number: TPS23881 Hi Sir
I want to design a PSE circuit with a power of more than 45W. A few questions below.
1. TPS23881 does not support autonomous mode, so does the design require an external MCU?
2. TPS23881 supports at, af and bt, so it is compatible…

Hi,
The GUI configuration is ok but the amplifier circuit is not correct.
PLL Sim ( www.ti.com/.../PLLATINUMSIM-SW) to design the loop filter.
TRIG2 is not needed.

Hello, I have another question. The chip I selected for the flyback circuit I designed has a built-in high-voltage startup circuit, so there is no need for an external high-voltage startup circuit to provide the initial voltage. The MOSFET I use is a…

Hello,According to the suggestion:"datasheet 19 page “The VSET voltage is applied using a DAC through a 20kΩ series resistor."
As shown below
test circuit :
Correction…
The URL of the image is as follows. D2 also no output .So where are these two circuit designs designed incorrectly

I think in place of R71, R63 and C144, you can keep a small rc filter mentioned as Rfa/Rfb and Cfa/Cfb in the datasheet, which are used to mitigate any unwanted noise seen by the CSA/CSB pin. You can take a look at the current sense transformer equivalent…
