Infineon Technologies' ICE2QR1765 is an offline quasi-resonant (QR) PWM controller designed for flyback converter topologies. This CoolSET™-Q1 series component features a 650V breakdown voltage and a 52kHz switching frequency, suitable for applications requiring efficient power conversion up to 56.4W. Internal switching is integrated, simplifying circuit design. The PG-DIP-8 package facilitates through-hole mounting. Key fault protection mechanisms include current limiting, overload, over-temperature, and over-voltage protection, enhancing system reliability. Operating across a wide temperature range of -40°C to 150°C (TJ), this isolated converter is utilized in power supplies for consumer electronics and industrial automation. The device operates with a 50% duty cycle and requires a supply voltage between 10.5V and 27V, with a 18V start-up voltage.
