Part Number: TPS62420EVM-167 Hi,
I'm having some difficulties with the TPS62420 concerning a sine wave oscillation on the current going through the inductor (Please see attach screenshot) when adding some load.(in respect with specs) You can see on …
Other Parts Discussed in Thread: TPS62420 Hello, when I open the tps62420evm eval software, I get the following:
after selecting "ok",
After selecting "yes,"
After selecting "ok,"
The "device is NOT operational" if I do…
Everything appears ok, so kindly show some waveforms of Vin, EN1, EN2, SW1, SW2, etc.
You could order the EVM here, if you just want a working board to test: www.ti.com/.../TPS62420EVM-167
You can find all the EVM documentation here: http://www.ti.com/tool/tps62420evm-167
The inductor value is 2.2uH and independent of the 1-wire interface.
Yes, you pick the output voltage from those tables in the D/S, when the interface is used.
Other Parts Discussed in Thread: TPS62410 , TPS62420 Q: Is there a TPS62410 EVM orderable on the web?
A: No but the TPS62410 and TPS62420 have the same package and pinout. Therefore, you can remove and replace the TPS62420 IC on the TPS62420EVM-167 with…
