TPL7407LEVM Performance Testing Using Lab Equipment
Output Parameter IOUT(on) Channel 1 Test Setup and Typical Results
Board setup: Sweep input voltage on J1-1. Set output voltage on J2-1 to 0.4V. Disconnect the relay supply
on TB1-4. Measure output current on J2-1 (sense connections at J2-1 and ground are highly
recommended to keep 0.4V on the EVM regardless of line losses in wires and current meter).
