Voltage Divider leverage factor

Looking at the blog entry that follows, this one is technically correct if rather peremptorily explained. Hysteretic controllers are actually quite simple. In Chapter 2 we discussed the leverage factor of a voltage divider. In this case the reference is 1.24V and Vom is 3.8V. So the leverage factor is 3.8/1.24 = 3.0645. So... 

The divider takes the voltage difference across its lower resistor (usually VREf) and leverages it by the factor total/ lower (where / Total is the sum of the two resistances), to give us the voltage across the entire divider (usually the output voltage).
