Product Overview

19V, 65W quasi resonant flyback adapter board. This 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 at 230VAC. The result is that this converter is compliant to energy star eligibility criteria. The flyback stage implements the new ST dedicated current mode controller L6566B, operating in quasi-resonant mode and detecting the transformer demagnetization by pin ZCD. The resistor on pin OSC sets the maximum switching frequency at about 165KHz. The power MOSFET is a standard 800V, STF7NM80 housed in TO-220FP package, needing just a small heat sink. The transformer is layer type, using a standard ferrite size EER28L, designed according to the EN60950.
  • Universal input mains range from 90VAC to 264VAC, frequency range from 45Hz to 65Hz
  • Output voltage of 19V at 3.42A continuous operation
  • Mains harmonics according to EN61000-3-2 class-D or JEITA-MITI Class-D
  • Stand-by mains consumption of 100mW at 230VAC
  • Average efficiency is better than 89% without synchronous rectification
  • EMI according to EN55022-Class-B
  • Safety according to EN60950
  • Dimension is 58mm x 121mm, components maximum height is 25mm
  • PCB is single side, 35µm, CEM-1, mixed PTH/SMT
