Notes:
1. Steady Date Voltage Regulation includes Initial Voltage Setpoint, Load Regulation, Output Ripple and Output Temperature Drift
and is measured at the converter’s output capacitors.
2. As measured at the converter’s output capacitors. For motherboard applications, the PCB layout should exhibit no more than
0.5m
