Part Number: TPS62421 I am using a fixed default output part (TPS62421) to generate 1.8V and 1.2V rails for a system.
I am seeing higher voltages (1.93V and 1.27V, respectively). As load increases, the voltage rises with 1.93V/1.27V being the maximum…
Part Number: TPS62421
I am using a fixed default output part (TPS62421) to generate 1.8V and 1.2V rails for a system. In certain low load scenarios I'm seeing the 1.8V output go unexpectedly high, up to 2.4V. I'm looking for any suggestions as to what…
I was looking at the EVM design and noticed that on the output grounds and both voltage outputs there is a split in the copper pour going to the headers (J4-J7). I haven't seen that done before and wondered why the board was designed like this.
Part Number: TPS62410 Other Parts Discussed in Thread: TPS62420 , TMS320F28377D , TPS62421 , TPS628511 Hello,
Our existing designs use TPS62420 to provide 1.2V and 3.3V to a TMS320F28377D MCU, plus other devices on the 3.3V rail. But it looks like stock…
Part Number: TPS62420 Other Parts Discussed in Thread: TPS62421 Hello!
I am a little confused when going through the TPS62420 datasheet and looking at the ability to use easyscale.
Section 8.3.5 DEF_1 Pin Functions - makes it seem that EasyScale…
Thanks for the input regarding DC/DC being the way to go.
I ferreted out a buck that would output 1.8V X 2, the TPS62421, and have replaced the LDO in my BOM with the TPS62421 and it's inductors and capacitors. The effect on the price was an extra buck…
