The EVL6566B-65W-QR is a demonstration board tailored on specification of a typical hi-end portable computer power supply. The peculiarities of this design are the very high average efficiency of about 90% without synchronous rectification and very low no load consumption of 100mW at230 Vac. The result is that this converter is compliant to energy star eligibility criteria. The fly back stage implements the new ST dedicated current mode controller L6566B, operating inquasi-resonant mode and detecting the transformer demagnetization by pin ZCD.
