Positive input connection from the input supply for the EVM.
Input voltage sense connections. Measure the input voltage at this point.
Return connection from the input supply for the EVM.
Filtered output voltage connection
Output voltage sense connections. Measure the output voltage at this point.
Output return connection
The PG output is on pin 1 of this header with a convenient ground on pin 2.
Use this SMA connector to measure the output voltage ripple before the second LC filter.
Use this SMA connector to measure the output voltage ripple after the second LC filter.
With the jumper removed, a clock signal can be applied on J5 to synchronize the IC's switching. To allow the IC to accept the applied SYNC signal, the jumper on J6 needs to be removed before applying the input voltage.
S-CONF pin input jumper. Place the supplied jumper across 2.2 MHz and S-CONF to operate the IC with a 2.2-MHz switching frequency without spread spectrum or output discharge. Place the jumper across 1 MHz and S-CONF to operate the IC with a 1-MHz switching frequency without spread spectrum or output discharge. Remove the jumper to operate the IC with the S-CONF settings set by R7 and to allow clock synchronization.
