Product details

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. Operating junction temperature spans -40°C to 125°C. Supply voltage range is 10 V to 25.5 V on Vcc/Vdd.

Frequently asked questions

What is the equivalent of ICE5AR4770BZSXKLA1?

The ICE3AR1080VJZXKLA1 is a functional peer in the CoolSET™ family with 800 V breakdown and 71 W output — a higher-power tier. For a direct replacement at the same 14.5 W level, no exact second-source MPN is listed; the ICE5AR4770BZSXKLA1 is the current active offering.

What are the protection features of ICE5AR4770BZSXKLA1?

The ICE5AR4770BZSXKLA1 integrates current limiting, open-loop protection, over-load protection, over-temperature shutdown, and over-voltage protection — covering the main fault modes of a flyback converter without external supervisory ICs.

What is the output power of ICE5AR4770BZSXKLA1?

Rated output power is 14.5 W, suitable for auxiliary supplies and low-power isolated AC-DC stages.

What is the switching frequency of ICE5AR4770BZSXKLA1?

The fixed switching frequency is 100 kHz, balancing transformer size and EMI filter complexity.
