LMR36015: RENB and RENT value

Kai Nomiyama

Part Number: LMR36015

Hi Team,

LMR36015 datasheet "10.2.1.2.9.1 External UVLO " describes "First, a value for RENB is chosen in the range of 10 kΩ to 100 kΩ".

Can we use lower RENB value like 1.6kΩ (< 10kΩ)?

I think that 10k ~100k resistor value is for noise sensitivity and good efficiency so if we use 1.6kΩ RENB, efficiency is getting worse but no any impact to device behavior.

Hi, Kai,

Yes, your understanding is right, The values are recommend range of 10 kΩ to 100 kΩ , this is to ensure no extra input current is lost to leakages. better to follow the datasheet, because we can't make sure it have no other issue working under overspec. Thank you.
