Other Parts Discussed in Thread: TPS54227 Dear Sir
We know TPS54227 Vin range is 4.5V~18V, but if we want work in Vin 8V~18V(TPS54227 turn on after Vin>=8V), may we use enable pin to control?
and how to calculate it? i can't see in datasheet. what we…
Other Parts Discussed in Thread: TPS54227 Hello,
My customer wants to know the equivalent circuit of the EN and VIN part of TPS54227.
Dose it have the Diodes (EN to VIN) for ESD protection?
Best Regards,

Hi Nison,
We are discussing this via email as well so we can continue there.
For future reference, below are the answers:
Please note TPS54227 has FCCM compared to PFM operation of the TPS54228 so efficiency at lighter loads with the TPS54227 will be…
Other Parts Discussed in Thread: TPS54228 I check yhe thest thermal resistance value and see someting not reasonable for me.
For example, the tps54228 TJA (Junction-to-ambient thermal resistance) is show 45.3°C/W and the TJC (Junction-to-ambient thermal…
