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 has been wiped out for the next year or so. Closest match I can find is the TPS62410. Here's the differences I can see from comparing datasheets:
1. TPS6242x datasheet covers both TPS62420 and TPS62421, the latter of which is a fixed output version. The TPS62410 datasheet also mentions a "fixed output version." Are both outputs of the TPS62410 settable via resistor dividers up until Vin?
2. TPS6242x is specified for output currents of 600/1000mA, TPS62410 is 800mA on both outputs. Not a problem for my use case.
Is there anything else I should be aware of? I saw several other posts regarding stability/overshoot issues with the TPS62410, maybe there's also some difference on the feedback side...?
Regards,
Mike
