2.1 EVM Connections

Working at an ESD-protected workstation, make sure that any wrist straps, bootstraps, or mats are connected and referencing the user to earth ground before power is applied to the EVM.

Table 2-1 EVM Power Connections
LABELDESCRIPTION
VIN+Positive input power connection
VIN–Negative input power connection
VIN_EMI+Positive input power connection for EMI test. The minimum operating voltage is 12V at this input.
VIN_EMI-Negative input power connection for EMI test. The minimum operating voltage is 12V at this input.
VOUT+Positive output power connection
VOUT–Negative output power connection
Table 2-2 EVM Signal Connections
LABEL DESCRIPTION
VINS+ Positive input sense pin for measuring efficiency.
VINS– Negative input sense pin for measuring efficiency.
VOUTS+ Positive output sense pin for measuring efficiency, and line and load regulation.
VOUTS– Negative output sense pin for measuring efficiency, and line and load regulation.
GND Ground reference point.
MODE Light load switching mode selection. Connect pin1 and pin2 for a FPWM mode . Connect pin2 and pin3 for an AUTO mode. Remove any jumper when external synchronization pulse is applied to SYNC.
VSEL Output voltage selection. Connect pin1 and pin2 for a fixed 5V output. Connect pin2 and pin3 for a fixed 3.3V output. Remove any jumper when programing the regulation target using an external resistor divider. Populate the external feedback resistor divider.
PG Probe point for power-good indicator. A pullup resistor is connected to VCC.
