It delivers up to 24 W of output power at a fixed 65 kHz switching frequency with a 75% maximum duty cycle, targeting isolated AC-DC power supplies for industrial and consumer applications. ## Fault protection set reduces external BOM The controller integrates current limiting, open-loop, overload, over-temperature, and over-voltage protection. This built-in suite eliminates several discrete supervisory components, simplifying the BOM and improving reliability in compact power supplies. ## 650 V breakdown — margin for universal AC input The 650 V breakdown rating on the integrated CoolMOS switch provides adequate margin for universal AC input (85–265 VAC) flyback designs, accommodating reflected voltage spikes and leakage inductance ringing without external snubber overdesign. The 10.5 V to 25 V Vcc supply range and 18 V startup threshold align with standard bias winding designs. ## Industrial temperature range and active lifecycle Rated for -40°C to 130°C junction temperature, the ICE3RBR4765JGXUMA1 suits enclosed or outdoor power supplies where ambient heat rises. The product status is Active per Infineon's lifecycle, with ROHS3 compliance. No last-time-buy risk; the part is available for new designs and production builds. ## 65 kHz fixed frequency — transformer and EMI trade-off The 65 kHz switching frequency is a common sweet spot for flyback converters: it keeps transformer core size manageable while staying below the 150 kHz conducted EMI threshold where filter design gets more aggressive. The 75% duty cycle maximum supports low-input-voltage operation with reasonable secondary-side voltage stress.","metaTitle":"Infineon ICE3RBR4765JGXUMA1 CoolSET Flyback, 24 W, 650 V","metaDescription":"Infineon ICE3RBR4765JGXUMA1 CoolSET offline flyback switcher: 24 W, 650 V breakdown, 65 kHz, 75% duty, 16-SOIC.
