High-performance SMPS current-mode controller with integrated 650 V CoolMOS® and startup cell. Ideal for low power offline switch-mode power supply designs requiring low standby power, overcurrent protection, soft start, and jittered switching for EMI reduction. The ICE3BR0665J (CoolSET®-F3R) from Infineon is a fixed-frequency current mode controller tailored for offline SMPS (switched mode power supplies). It integrates a 650 V avalanche-rugged CoolMOS® transistor and startup cell into a DIP-8 package, reducing external component count while offering robust protection and efficiency features.
