LT8392 CTRL pin threshold voltage

Question

Hi ADIexpert 
 when in LT8392 paralleled mode 
 is it 0.3V or 0.25V CTRL pin threshold voltage that the slave LT8392 would start to work? 
 in the datasheet of LT8392, I can see both value in different places

thank you 
 Ken

Hi Ken, 
 0.25V is the right value. Datasheet shows 0.3V as the output current might not change linearly when CTRL is below 0.3V. Also, regulation error is large when CTRL is that low.
