Flyback: Buck for Automotive (4.5V @ 0.05A)

Description

A triple-output non-isolated flyback converter provides a regulated low voltage and two high voltage rails. A buck converter with an input transient voltage-clamping circuit produces a 5V rail. The addition of a dithering circuit creates spread-spectrum operation on the switching frequency to lower EMI: making this circuit suitable for automotive use.
