3 Connector and Test Point

3.1 Input Connectors

3.1.1 J1: VIN

This header is the positive connection to the input power supply. The power supply must be connected

between these pins and J3 (GND). Twist the leads to the input supply and keep them as short as possible.

The input voltage must be as provided in Table 1.

3.1.2 J2: Input Sense Connector

This header is intended to measure the input voltage directly on the input capacitor. Therefore, a four-wire

power and sense supply can be connected. Twist the leads to the sensing connector.

3.1.3 J3: GND

This header is the return connection to the input power supply. Connect the power supply between these

pins and J1 (V

). Twist the leads to the input supply and keep them as short as possible. The input

voltage must be as shown in Table 1.

3.2 Output Connectors

3.2.1 J4: VOUT

This header is the positive connection of the output voltage. Connect the load between these pins and J6

(GND).

3.2.2 J5: Output Sense Connector

This header is intended to measure the output voltage directly on the output capacitors.

3.2.3 J6: GND

This header is the return connection of the output voltage. Connect the load between these pins and J4

OUT

3.3 Other Connectors

3.3.1 J7: SMA Output Connector

This SMA connector is connected to the output voltage of the converter. It can be used to analyze the

noise spectrum of the output voltage with a spectrum analyzer. By default, J7 is not assembled on the

EVM.

3.3.2 J8 SMA Input Connector

This SMA connector is connected to the input voltage of the converter. It can be used to analyze the noise

spectrum of the input voltage with a spectrum analyzer. By default, J8 is not assembled on the EVM.
