The fixed 65 kHz switching frequency is a standard sweet spot: high enough to keep the transformer core small, low enough to avoid excessive switching losses in the integrated MOSFET. The 75% maximum duty cycle (typical for flyback) sets the transformer turns ratio and primary inductance. At 43 W continuous output, plan for a heatsink or adequate PCB copper area — the PG-DIP-7-1 package relies on the board for thermal spreading. ## Supply range and startup behaviour The Vcc supply range of 10.5 V to 25 V covers the bias winding output of a typical flyback. The 17 V startup threshold ensures the controller begins switching only after the bulk capacitor has charged sufficiently, preventing hiccup at low line. The undervoltage lockout (implied by the range) drops out below 10.5 V, so the bias winding must hold above that during normal operation. ## Lifecycle and sourcing The ICE3BR2280JZXKLA1 is listed as Active with ROHS3 compliance.","metaTitle":"Infineon ICE3BR2280JZXKLA1 CoolSET Flyback","metaDescription":"Infineon ICE3BR2280JZXKLA1 CoolSET®F3R80 offline flyback switch, 800V breakdown, 43W, 65kHz, PG-DIP-7-1.
