5.1.4 Recommended Wire Gauge

VIN to J2

The connection between the source voltage, VIN, and J2 of EVM can carry as much as 5 ADC. The minimum recommended wire size is AWG #16. Shorter lengths of input wire will aid in reducing inductance and provide better overall performance.

J5 to LOAD1 (Power Pins 2 and 3)

The power connection between J5 of EVM and LOAD1 can carry as much as 10 ADC. It is recommended that the user use AWG#16 wire. It is recommended that the load wires be kept as short as possible. This will aid in performance, most notably in transient response.

J2 to LOAD1 (Remote Sense)

If remote sense is to be used, ensure that J6 and J7 are in the remote sense enable position (shunt pins 1 and 2).Load wires and sense wires should be kept less than six inches to ensure proper functionality. The remote sense wires connecting J5 (pins 1 and 4) and LOAD1 carry less than 1 ADC. The minimum recommended wire size is AWG #22 with the total length of less than six inches long.
