Abstract :
Analytical equations are derived for a power supply system at high slew-rate load current transients. The analyzed model includes a synchronous buck converter, controller, output capacitor and supply bus parasitics. The impacts of system parameters on output voltage transient response are studied. An optimization procedure for power supply system design is suggested. Finally, influence of controller limitations on transient response characteristics is evaluated. Analytically derived waveforms are in good agreement with measurements
