Part Number: LM61435-Q1

Hi team,

Customer would like to use LM61435-Q1 in 24Vinput , 12V/1A output application.

Their target frequency is 2.1MHz.

Could you help recommend the inductor, output capacitor, Cff value for their application?

Thanks and Best Regards,

Hi Will,

I would recommend the following

LOUT=3.3uH

COUT=22uF

CFF=DNP

Hi Marshall,

Using 3.3uH would get 87% ripple. Does this recommended value?

Datasheet recommend 20%~40% of maximum output current, how to understand we recommend 3.3uH and get 87% ripple?

Thanks and Best Regards,

Will

Hi Will,

You want to do the calculation at the full-rated load current of the device.
