Part Number: TPS62821 Hello,
On my design the enable pin of the buck converter TPS62821 is controlled by a µC, but before the µC is programmed the EN pin is leave floated and VIN is powered.
During this time, the output of the buck converter…
Part Number: TPS62821 Tool/software: WEBENCH® Design Tools Hi,
I'm from HCL technologies, while running the simulation for TPS62821 IC in WEBENCH tool I can't able to view the simulation output for -- START UP -- simulation only, the part numbers…
Part Number: TPS62821 Dear Sir,
Please help to check below waveform about TPS62821 Vout and Iout. Is it normal for the output voltage to rise again after falling? Is this the behavior of the switching current limit?
Best Regards,
Sam
Part Number: TPS62821 Hello team,
Hope you are doing well. When you get a chance can you help with customer question on if the TPS62821DLC has a 1.2V Fixed version?

Part Number: TPS62821 Other Parts Discussed in Thread: TPS62825 , TPS82084 Hi,
I’m working on a core power supply for a small FPGA and I have a few questions about some parts.
The requirements are:
Vin: 2.8 – 4.5V
Vout: 1.1V +/- 2.5%
Iout:…
Part Number: TPS62821 Are there any app notes with calculations that model the AC response for DCS control converters? I have a customer that wants to do some hand calculations for TPS62821, beyond the TINA simulation.
Thanks,
Michael
Part Number: TPS62821 Hi,
I didn't find the measured output ripple in datasheet. Could you pls provide the ripple data with below condition? Thanks.
Vin=3.3V Vout=1.5V Iout=50-300mA L=0.47uH Cout=22uF
Part Number: TPS62821 Dear E2E:
Compared to the schematic and pcb layout, i found the via near L99 in wrong position, i should be behind the output cap C741. The input cap C739 was not very perfecter.
I check the sw waveform, it's bad. The output point…
Part Number: TPS62821 Hello,
I have a customer that is using the TPS68281 device and they would like to use a larger inductor than specified in the datasheet: a value between 1-3µH. They have 5V in, 3.3V out at 10-50mA.
The datasheet "Inductor Selection…

Hi, guys. I'm thinking of using the TPS62821 to provide 3.3V to power up the MSP432 MCU. I'm creating a custom PCB that uses 5V micro USB power. Thanks to the WEBENCH tool,
I referred this and created my schematic using…
