LM25141-Q1: VIN UVLO

Scarlett Cao

Part Number: LM25141-Q1

Hi team,

My customer asks whether LM25141-Q1 has input voltage UVLO function. From datasheet I only see UVLO of VCC and VDDA. Could you please help confirm that?

Thanks,

Scarlett

Hi Scarlett,

There is LDO from VIN to VCC, as the VCC current is quite small before circuit start switching, so VIN UVLO is almost same as VCC UVLO, which means VIN UVLO rising is 3.4V typical and hysteresis is 175mV.
