Beschreibung W adapter demo boardUsing the new 800 V CoolMOS™ P7 and ICE2QS03G quasi-resonant PWMcontrollerThis 45 Wadapter demo board is intended to be a form, fit and function test platformfor charger and adapter applications to show the operation of the 800 V CoolMOS™ P7 as well as the overall controller design. The demo board is designed around a quasi-resonant flyback topology for improved switching losses which allows higher power density designs and lower radiated and conducted emissions. A 45 Wuniversal input isolated flyback demo board with a 19 V output based on the ICE2QS03G controller and the P7 MOSFET is described in this application note and test results are presented.
