The Power Integrations TOPSwitch®-HX series TOP258LN is an offline switcher IC designed for flyback topologies. This component features a 700V breakdown voltage and supports switching frequencies of 66kHz and 132kHz, with a typical duty cycle of 78%. Integrated fault protection includes current limiting, over-temperature, and over-voltage protection for robust operation. The TOP258LN is packaged in an eSIP-7F (7-SSIP, 6 leads, exposed pad, formed leads) for through-hole mounting. This device is suitable for high-power applications up to 122W and finds utility in power supplies for consumer electronics, industrial control systems, and off-line power conversion. The device offers isolated output and operates within a temperature range of -40°C to 150°C (TJ).
