Hi Vignesh,
Pulling the MODE pin high forces the converter to operate in fixed frequency PWM mode even at light load currents but the efficiency is lower compared to the power save mode during light loads. Which means, the device will be in PWM mode…
Hi Allan-san,
Thank you for the detailed information.
TPS62290 is a power device, so could you please tell us what I need to do specifically if performing the temperature humidity testing for the power devices ?
Best regards, Kato
Hi Febin-san,
Thank you for the information.
I have an additional quesiton, so could you please tell me the minimum pulse width for EN pin when the EN pin is asserted and de-asserted? For example, does TPS62290 start up normally if the high level…
Hi Chris Glaser-san
Thank you for your reply.
I have to apologize to you.
Input & output true condition is here.
1) 5Vin 3.3V 0.6A
2) 5Vin 2.5V 0.1A
3) 5Vin 1.8V 0.5A
The TPS62290 function of my favorite is this.
"Forced PWM"

Part Number: TPS62290-Q1 Hi Team,
I found contradiction between the text and table.
As text's meaning, MODE PIN =0, PFM mode at light load.
Is it opposite in table?
Part Number: TPS62290-Q1 Dear support team
My customer want to actual effiency data of light load.
Could you provide it ?
◆TPS62290-Q1 Vin=3.3V Vout=1.2V Iout=100uA (PFM mode)

Part Number: TPS62290 Hello,
For about the feedback divider network Resistance. The datasheet of TPS62290 promote R1=360K and R2=180K, But Our customer think that a smaller resistance is more suitable and more Stable and reliable. like under 100kΩ.…
Part Number: TPS62290-Q1 Other Parts Discussed in Thread: TPS62293-Q1 Hi team,
Could you let me know the difference clearly between TPS6229 0T DRVRQ1 and TPS6229 3T DRVRQ1? According to the datasheet, it seems there is no difference.
Regards,

Hello,
from the waveform and the low impedance between the sw pin and gnd, it is clear that the low side is damaged. Unfortunately is not easy to understand well the behavior of the device after such event because could be whatever. In example from…
Hi team,
My customer uses below application. And I have two questions as below,
1. They want to use smaller resistor, R1=150k, R2=33k, is it ok? Then if they use these two resistors, could you please recommend the C1 value? 33pF?
2. As we know,…
