Other Parts Discussed in Thread: TPS54526

Dear Team,

What is the max output current we can get from TPS54526 when output =3.3V and input=5V.

As per datasheet it says 5.5A but i want to know Is this current rating changes with output and input voltage we apply.

Regards,

I will move your question to non-isolated forum, where this part is better supported.

Hi, Prasanna G,

The max output current we can get under 5Vin, 3.3Vo is 5.5A.

generally speaking, it won't change with output and input voltage. unless the set up triggers minimum duty cycle or maximum duty cycle,

while in your case, 5Vin to 3.3Vo, it's fine.

Hello Nick,

Thank you for the information.

May i know briefly about " unless the set up triggers minimum duty cycle or maximum duty cycle," how this will effects.
