9.9 Enable Resistors, Ren1, Ren2

The LM27402 evaluation board is equipped with an enable connection tied directly to EN. Resistor footprints Ren1 and Ren2 provide an optional voltage divider network from VIN to GND to program the LM27402 to enable at a certain input voltage. The following equation will guide the user in choosing resistors values to create a resistor divider for EN:
