Hi team,

I'd like to choose a boost controller that can support 360W output, Vin is 14.4V.

Can LM5122-Q1 can meet the requirement?

Or what device to you recommend in this case?

Thank you!

Hi Yinsong,

This is an external Audio Amp project, the output will support 30W * 4CH 4 ohms + 60W × 1 sub 4 ohms, the Audio Amp output is 1 % distortion effective power (sine wave, so the peak power would be 2 times larger), so the boost need support 360W outpower,

The customer decide to evaluate LM5122-Q1 and LM5123-Q1.

Thanks for your reply.

Regard,

Ivy

Hi Ivy,

Thank you for the information. So what is the bias/VCC voltage of the audio amplifier? That is where the boost output is connected to, right?

Thanks,
