It delivers up to 30 W in isolated flyback topologies, switching at 52 kHz with a 50% maximum duty cycle. Built-in fault protections — current limiting, over-load, over-temperature, and over-voltage — reduce external supervision circuitry. The part is part of the CoolSET™-Q1 family, designed for industrial and automotive-grade power supplies where junction temperatures can reach 150°C. ## 650 V breakdown and 30 W — sizing the primary side The 650 V drain-source breakdown voltage handles reflected voltage and leakage spikes in flyback designs. The 30 W output power is a practical limit for auxiliary supplies, bias rails, and small offline converters. ## Through-hole PG-DIP-8 — board layout and thermal management The PG-DIP-8 package is a through-hole 8-pin DIP with 0.300-inch (7.62 mm) row spacing. It suits single-sided boards, prototyping, and designs where wave-soldering is preferred over SMT reflow. The DIP package's copper leadframe provides moderate heat dissipation; for 30 W output, adequate copper area on the PCB and airflow — or forced cooling in enclosed supplies — is recommended. The tube shipping medium is typical for through-hole parts; reeling is not available for this package variant.","metaTitle":"Infineon ICE2QR4765XKLA1 CoolSET Flyback Switcher, 650V, 30W","metaDescription":"Infineon ICE2QR4765XKLA1 offline flyback switcher, 650V breakdown, 30W, 52kHz, -40 to 150°C.

For a higher-power through-hole alternative in the same package, the ICE3BR0665JXKLA1 (74 W, 65 kHz, CoolSET F3R) is a functional upgrade but uses a different control scheme. For surface-mount, the ICE2QR2280G1XUMA1 (53 W, 800 V) or ICE2QR1080GXUMA1 (77 W, 800 V) are options with a higher breakdown voltage."},{"question":"Can ICE2QR4765XKLA1 be used in 24V designs?","answer":"Yes. The Vcc supply range is 10.5 V to 27 V, which covers 24 V bias rails. The 18 V start-up threshold is within that range. The 30 W output power is sufficient for many 24 V auxiliary supplies."},{"question":"Where can I buy ICE2QR4765XKLA1 with reliable lead time?","answer":"Contact our sales team for current lead time and availability.
