External Tracking Selection
The external tracking can be configured by J5. If jumper J5 is shorted, the internal 2-V VREF voltage is
used to set the target output voltage to be 0.75 V. If jumper J5 is open, the external reference between 1.2
V to 4.0 V can be applied to J7. The output voltage will be regulated to ½ of the external reference
voltage. For example, applying 1.35 V to J7, the output voltage is 0.675 V.
