Test Points
•
VINEMI - Input supply to EVM. Connect to a suitable input supply.
•
GND - System power ground
•
VOUT - Power output of EVM. Connect to desired load.
•
VOS - Output voltage sense connection. Connect to DMM.
•
VINS - Input voltage sense connection. Connect to DMM.
•
GNDS - Ground sense point for analog measurements. Connect to DMM.
•
EN - Connected to the EN input of the device
•
RESET - Connected to the RESET pin of the IC. It is used as a flag output. The reset function can be
monitored at this test point. Pull-up resistor, RPU, must be populated. A typical value for pullup resistor
is 100 kΩ.
•
SYNC/MODE - Connected to the SYNC/MODE pin of the IC.
•
VCC - Connected to the VCC output of the device. Can be used for logic level pullups, if needed.
•
OPEN PADS - Connections for frequency response analyzer (on bottom of board) to take Bode plots.
