(1) Nodes on the EVM can have high spikes above the input voltage (in buck mode) or output voltage (in boost mode) level due to the high di/dt and dv/dt electrical flow associated with switch-mode power supplies. Switch node voltage can swing up to input or output + inductive spike level. High-side gate drives can swing up to switch node voltage + 11 V (DRV_SUP supply voltage dependent) + gate drive inductive spike level. Observe safety precautions at all times.
(2) Connectors, bump-ons, and jumpers on the EVM are not good choices for evaluation under temperatures that greatly deviate from a room temperature of 25°C. Refer to the Bill of Materials (BOM) for temperature ratings of board components.
(3) TI recommends thermal monitoring (for example, using a thermal camera) if the power-stage output current > 5A or total output power > 100W.
(4) The default EVM input current limit is set to 20A through the IIN pin. The current-limiting feature can be adjusted by setting the EN_IIN_PIN bit to '0', changing the IIN pin resistor, or shorting the IIN pin to PGND through JP11.
