GND and attach an I

C interface using one of the methods described in Section 5.
5 External Control Interface
There are two methods for controlling the LM3528 evaluation board. The first option is via a Texas
Instruments USB interface board. The second option is by using the SDA and SCL headers available on
the upper left corner of the board. When option 1 is used, the USBL and USBR connectors plug directly
into a Texas Instruments USB interface board. The connectors are keyed so they will only fit one way. On
the LM3528 evaluation board the V
IN
/VUSB jumper allows for power to come from IN or from the USB .
