Part Number: TPS54561EVM-555 Tool/software: Hello,
There is an issue in the TPS54561EVM-555 schematic design. The maximum voltage for the EN pin of the TPS54561DPR is 8.4V DC, but the voltage divider used on your EVM board exceeds this value. Although…
Part Number: TPS54561EVM-555 Hello,
Can you send me the design files for the TPS54561EVM including layout.
Also can the TPS54561EVM output 26V at 2A with modifying the passive components (not including FET)?
Thanks!
Part Number: TPS54561EVM-555 Hi,
The Datasheet specifies maximum (Abs Max) of 8.4V and On the EVK input range is from 7-60V.
Resistor divider network is been used to set the Minimum operating Voltage.
But At 60V max, EN reads a voltage of 10.5 which…
Part Number: TPS54561EVM-555 Other Parts Discussed in Thread: TPS54561 The TPS54561 is intended to be used to both provide 6.9VDC at 3.5 Amps and also charge a 6 Volt Sealed Lead Acid battery.
The switcher circuit is replacing the regulator section…
Part Number: TPS54561 Hello,
Q1:

Dear Iven,
Thanks for your reply! Please find my inline replies.
1. According to the datasheet, the test board of derating limits is similar to the TPS54561EVM-555 evaluation module, so you can refer to the board but it's hard to guarantee a same…
first of all, Thank you very much for the quick response.
the tests were done on your evaluation board ( TPS54561EVM-555 ).
and the value of the resistive is Between 1.2 and 1.5 ohm.
If more information is needed, I'll be glad to share.
