DVD player multi-output power circuit design

Summary:

working principle

The TinySwitch-PK multi-output power supply delivers 7.5W of continuous output power and 13W of peak power. Typical applications include DVD players or set-top boxes, which all require the use of multiple output flyback power supplies.

design feature

  • Multiple output power supply
  • Excellent cross voltage regulation
  • Two-way output weighted regulation
  • Extremely energy efficient
  • Output power is 0.6 W at input power of 1 W
  • Low no-load power consumption (< 150 mW at 230 VAC AC input)
  • Meets CEC/Energy Star 2008 requirements for load efficiency (required 68.1%, actual 77.7%)
  • Compliant with CISPR-22/EN55022B conducted EMI limits, EMI margin >10 dBmV
  • Automatic restart function allows unlimited short-circuit output
