Output ripple and noise in power module device while in very light load...

Peter Tseng

Dears,

My customer wants to know how about the output ripple and noise of power module device if they used in light load around 100~200mA output current?

Will that be the problem with such design? If power module solution suitable for light load design?

Thanks.

Hello

Please give us your complete application specification; such as input voltage, output voltage, and load current range.

Thanks

Hi Sir,

The input is 5V and output is 3.3V or 1.8V with around 100mA~150mA Iout.

Thanks.

Hello

We have many converters that can cover that range of application requirements.

Most converters will be in PFM in that load range, but the ripple will depend on the

particular architecture.

You will need to search our website for a suitable regulator and then get an EVM to test.

Thanks
