indicated in Figure 1 and set the supply to the desired voltage. The device disable
current may be measured in this configuration.

• Banana jacks are provided for V
• A jumper is provided for controlling the Enable signal. Enable may also be
• A jumper is also provided to connect a POK pull-up resistor to the input supply.
• Foot print is also provided for a SMA connector to SYNC input. A switching input
• The board comes with input decoupling and reverse polarity protection to guard

controlled using an external switching source by removing the jumper and
applying the enable signal to the ENA clip-on terminal.
This jumper is especially useful to measure the disable current and eliminates
having to subtract the current drawn by the POK resistor.
to this pin allows the device clock to be phase locked to an external signal. This
external clock synchronization allows for moving any offending beat frequency to
be moved out-of-band. A swept frequency applied to this pin results in spread
spectrum operation and reduces the peaks in the noise spectrum of emitted EMI.
the device against common setup mishaps.
Set the “ENABLE” jumper to the Disable Position, as shown in Figure 1.
Connect Power Supply to the input power connectors, VIN (+) and GND (-) as

Figure 1: Shows POK, Enable, VDROOP and SYNC/LLM Jumpers.
POK PWR jumper as shown connects the pull-up resistor to VIN.
Enable jumper shown is in DISABLE position. SYNC/LLM jumper as
shown ties this pin Low. VDROOP jumper as shown is low, and
should stay grounded.
