(1) Due to the high di/dt and dv/dt
electrical flow associated with switch-mode power supplies, nodes on the EVM can
have high spike above input voltage (in buck mode) or output voltage (in boost
mode) level. 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. Safety
precautions must be observed at all times.
(2) Connectors, bump-ons, jumpers on the EVM are not a good choice for evaluation
under temperature greatly deviated from room temperature of 25°C. Please refer
to BOM for temperature rating of board components.
(3) Thermal monitoring (for example,
using a thermal camera) is recommended if power stage output current > 5 A or
total output power > 100 W.
(4) Default EVM input current limit is set to 8 A through the IIN pin. The current
limiting feature can be disabled by setting EN_IIN_PIN bit to '0', changing IIN
pin resistor, or shorting IIN pin to PGND through JP11.
