It delivers 14.5 W of output power at a fixed 100 kHz switching frequency, with a duty cycle limit of 75%. The part is designed for isolated AC-DC converter stages in industrial auxiliary supplies, appliance power boards, and IoT gateway power bricks — anywhere a compact, monitored flyback stage is needed with minimal external components. ## 700 V breakdown and full protection set The 700 V breakdown voltage handles line transients on universal mains. The controller integrates current limiting, open-loop, over-load, over-temperature, and over-voltage fault protection. The 100 kHz switching frequency balances transformer size and EMI filter complexity. ## Through-hole PG-DIP-7 for serviceable designs The PG-DIP-7 package is through-hole, suited for hand-assembled or field-repaired power boards. The 7-lead DIP footprint fits standard 0.300\" (7.62 mm) pitch sockets or wave-solder layouts. Operating junction temperature spans -40°C to 125°C. Supply voltage range is 10 V to 25.5 V on Vcc/Vdd.","metaTitle":"Infineon ICE5AR4770BZSXKLA1 Flyback Switcher, 700V, 14.5W","metaDescription":"ICE5AR4770BZSXKLA1 CoolSET flyback switcher: 700V breakdown, 14.5W output, 100kHz switching, PG-DIP-7.
