【摘要】 COOLMOSICE2A165/265/365是Infineontechnologies公司推出的系列PWM +MOSFET二合一芯片 ,其突出特点是由其组成的开关电源 ,在市电电网中工作时 ,无需外加散热器即可输出20～50W的输出功率 ;且能自动降低空载时的工作频率 ,从而降低待机状态的损耗 ;同时还具有过、欠压保护、过热保护、过流保护以及自恢复功能 ,因而在中小功率开关电源中有着广泛的应用前景。更多还原

【Abstract】 COOLMOS ICE2A Family IC is combined PWMwithMOSFET,which are produced by Infineon techˉnologies CO.,and has multiple characterisitics of output power20-50W in normal Line,no heat sink reˉquired,multi protection function,only few external components required in SMPS;The frequency reduction can be automatic in no load to avoid audible noise and standby power consummate,and hence it can be applied broad in middle and small power SMPS.更多还原
