Part Number: TPS562201 Tool/software: Hi, My customer is asking about following change for your datasheet of TPS56220x. * We have three points. 1. Why did you change "Fsw" conditon from "Vin=12V, Vo = 1.05V, FCCM mode" to "Vin=12V, Vo=3.3V, Io=1A" in datasheet…
Part Number: TPS562201 Tool/software: Due to the data sheet update, the REN has changed. Changes from Revision B (September 2020) to Revision C (April 2024)
It seems that REN (EN pin resistance to GND) will change from Max 900Ω to 2400kΩ,and in order…
Part Number: TPS562201 Tool/software: Could you help to explain what VFB=0.9V means?
Because the internal FB voltage is nearly 0.77V, so it is 0.9V external DC source connected to FB PIN?
Part Number: TPS562201 Tool/software: Hi experts,
our customer have additional question about original thread.
Chen said as followings
> EN pin voltage higher than VIN pin when turn-off input voltage, so you need to add clamp diode between EN and VIN…
Part Number: TPS562201 Tool/software: Hi,
i have added 18PF cap at VFB pin side.and in next ver i removed it.
i am simulating this in ansys,now i am facing issue is with 18PF it is coming good,and without it is having wrong output.
can you explain me…
Part Number: TPS562201 Tool/software: Hi ,
I would like to understand the what is the significance of the C8 capacitor in the design which is not mounted in the Datasheet. And also I could not find much information about it in the datasheet. But we ran…
Part Number: TPS562201 Other Parts Discussed in Thread: TPS562208 Tool/software: Hi ,
I have used the recommended design in the Datasheet and have used in the feedback resistor value 10k and 57.6k for generating around 5.4 V.
and used 3.3u H with DC…
Part Number: TPS562201 Other Parts Discussed in Thread: TPS62902 , TPS562203 Tool/software: Hi Team ,
We are designing a handheld device which is driven by a 12 V battery . It is a ESP32-S3-WROOM-1-N8R8 based board (3.3V) . Request your suggestions to select…
