LM251772: Minimum switching duty

Kailun Liu

Part Number: LM251772

Hi Team,

Can you help to check whether LM251772 can support "0" switching duty? (24V VIN, 24V VOUT)

Hi Kailun,

not sure what you exactly mean with "0" duty cycle.

Do you mean the support of 100% Buck or 100% Boost mode? If so, then the device does support that with the integrated charge sharing circuit..

If not please provide more details and conditions for that requirement.

Best regards,

Stefan

Hi Stefan,

Thanks for your response!

I mean Vin=Vin, the Vin will directly pass to Vout.

Hi Kailun,

yes, this is supported by the ACM mode - please see datasheet for more details.

Best regards,

Stefan
