Page 5: Jumper Configuration Details For Each Board
The EN selection jumper allows the user to select the desired enabling scheme for the end application. The LMZM23600 and LMZM23601 feature a precision enable input which can be used to set the input UVLO point with a voltage divider from the input voltage. Alternatively, the enable input can be driven by a logic signal or it could be tied directly to VIN for an always-on operation. -
