LM25118: Max Duty Cycle

Naizeng Wang

Part Number: LM25118

Hi team,

If both the input voltage and output voltage of my application are 20V. Can LM25118 work well?

Best regards,

Hi Naizeng,

The LM25118 is a buck-boost controller, so Vin = Vout corresponds to a 50% duty cycle condition - should work fine.

Hi Nison,

It is a buck-boost circuit, namely the input voltage can be higher or lower than the output voltage setting point. So, it works for your case.

Thanks,
