The only difference is it has a lower Vcc turn off threshold. The Cool SETTMQ1 is the first generation of quasi-resonant controller and Cool MOSTM integrated power IC. Operating the MOSFET switch in quasi-resonant mode, lower EMI, higher efficiency and lower voltage stress on secondary diodes are expected for the SMPS. Based on the Bi CMOS technology, the Cool SETTM-Q1 series has a wide operation range (up to 25V) of IC power supply and lower power consumption. It also offers many advantages such as quasi-resonant operation till very low load, increasing the higher average system efficiency pared to other conventional solutions, achieving ultra-low power consumption with small and controllable...
