Overview

This power reference design generates all voltages to supply a class-D audio amplifier. The main output voltage is 30V and delivers 200W continuously and 750W peak. The first stage is a power-factor corrected Boost. A Flyback converter supplies 12V on primary side as well as 12V@300mA and 3.3V@200mA on secondary side. A hardware switch + remote input let the converter enter in stand-by mode: in this status the 30V output is disabled while 12V, 3.3V are "always on". This way the stand-by power is reduced further. A second digital input switches the main output voltage from 30V to 18V, allowing low current consumption mode in case of the audio amplifier needs less power.

Features
  • Low cost PFC + 2-switch forward topology provides 200W average, 750W peak power
  • Constant switching frequency: particularly suitable for audio applications
  • Good plug-to-plug efficiency:  85% @ 115Vac, 87% @ 230Vac
  • Compact construction:  88mm x 173mm, height 35mm
