Figure 28. Resistor Configuration to Enable DC-DC
1. MUST SWITCH R35 to Rtps1
2. MUST SWITCH R34 to Rtps2
3. Populate Rtps
4. DC-DC circuitry was optimized for efficiency for 5 to 8 V, but a voltage of 3.3 V to 17 V can be applied
to VCC SMA after resistor network is configured correctly from steps above.
