Part Number: TPS62420 Hi team,
Here`s an issue from Converter 2 Adjustable Default Output Voltage Setting
If you look at the datasheet, there is a formula to calculate the output voltage.
VOUT=VREF*(1+R21/R22)=0.6∗(1+205k/200k)=1.215
If R21 is…
Part Number: TPS62420 Tool/software: Hi
I am using TPS62420DRC ,and now am getting a sprctrum as shown in below and spacing between each peak is near to 2.25 MHz which is the switching frequency of TPS62420DRC.
I am failing RE at 190 and 228 Mhz.…

Hi Febin,
I made several tests (lowering the values of the resistors to set the voltage, changing bypass and output capacitors...) and the problem remains exactly the same.
I´ve decided to change the TPS62420 for two TPS56628DDAR, one for each rail…
Part Number: TPS62420-Q1 Hi team,
Could you please help check if we have Functional Safety FIT Rate and Failure Mode Distribution of TPS62420-Q1?
Thanks,

Part Number: TPS62420 Hello
If I remove Cff, will it affect SW1 as well?
The waveform on the left is when Cff is removed, and the waveform on the right is when it is mounted.
SW1 : 3.3V
SW2 : 1.2V
Can oscillation occur in SW1 by removing Cff…
Part Number: TPS62420 Other Parts Discussed in Thread: TLV62080 Hi,
we are currently using TPS62420 in one of our designs as a supply for the F28388D and some other peripherals. More precisely, we are generating 3V3 with converter #1 and 1V2 with converter…
