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 is suitable for automotive use.
