Flyback switcher for 14.5 W isolated supplies
The Infineon ICE5AR4770BZSXKLA1 is a CoolSET™ offline flyback switcher integrating a 700 V avalanche-rated MOSFET and PWM controller in a 7-lead PG-DIP-7 through-hole package. 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. Supply voltage range is 10 V to 25.5 V on Vcc/Vdd.
