ICE2QR2280G-1中文资料英飞凌数据手册PDF规格书

Description

The ICE2QR2280G-1 is derived from CoolSETTM-Q1. The only difference is it has a lower Vcc turn off threshold. The CoolSETTM-Q1 is the first generation of quasi-resonant controller and CoolMOSTM 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 BiCMOS technology, the CoolSETTM-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 compared to other conventional solutions, achieving ultra-low power consumption with small and controllable output voltage ripple at standby mode with Active Burst Mode operation, etc.
