Description

This reference design provides a compact power solution for 70W (peak) audio systems. This supply accepts a universal AC input, and uses a UCC28610 quasi-resonant flyback controller to generate an isolated 24V. Auxiliary 5V/1.5A and 3.3V/0.1A outputs are also provided. This design is capable of providing power to sustained loads of 30W and peak power loads of 70W with efficiencies up to 85%.
