POWER MANAGEMENT

7. Switching Spikes. Switching spikes will also occur due

to distributive capacitance across turns of the inductor

when combined with output capacitor series inductance

(ESL). Reduction to a level at or below the switching ripple

can be achieved by using a post filter as shown below.
