... Description Introduction The EVALSF2-ICE2B765P demoboard is a low cost flyback switching power supply using the ICE2B765P integrated circuit from the CoolSET 24V, 80W supply that operates from an line input voltage range 265V applications requiring either an open frame supply or an enclosed adapter. Line Input The AC line input side comprises of an input fuse F1 as line input over current protection as well as choke L5 and the X2 capacitors C8 and C24 as radio interference suppressors ...

... In order to reduce the conducted EMI behavior, capacitor C7 is set in parallel to the transformer TR1. Note: The value should not exceeds 2.2nF in order to guarantee a safety off line switch mode power supply design. www.Infineon.com/CoolSET 80W 24V Adapter with ICE2B765P on Board Page 7 from 22 EVALSF2-ICE2B765P V2.3 ...
