Notes:
1. Steady State Voltage Regulation includes Initial Voltage Setpoint, DC load regulation, outut ripple/noise and temperature drift.
2. These specifications assume a minimum of 20, 1
μ
F ceramic capacitors are placed directly next to the CPU in order to provide
adequate high-speed decoupling. For motherboard applications, the PCB layout must exhibit no more than 0.5m
resistance and 1nH parasitic inductance between the converter output and the CPU.
