Power Integrations High Side Off Liner Power Switch IC 8-Pin DIP-C TOP257PN

Power Integrations TOP257PN High Side Off Liner Power Switch IC 8-Pin DIP-C is a highly integrated monolithic off-line switcher IC designed specifically for off-line power supplies. It enables power supply designs up to 195 watts while ensuring high efficiency under all load conditions, including low load and standby modes.

This IC supports multi-mode operation that maximizes efficiency across all load ranges, eliminating the need for a heatsink up to 35 watts depending on the package used, making it ideal for compact and efficient designs.

Key protective features include output overvoltage protection to safeguard the components, line undervoltage detection to prevent turn-off glitches, and line overvoltage shutdown to extend line surge limits, enhancing reliability and safety in demanding industrial and commercial applications.

The device integrates an accurate programmable current limit and optimized line feed-forward for superior line ripple rejection, further improving performance. The integrated soft-start function minimizes start-up electrical stress, extending the lifespan of connected components.

With an operating temperature range from -40°C to 150°C, the TOP257PN is suited for demanding environmental conditions. Its through-hole mounting and compact 8-pin DIP-C package make it suitable for various industrial, electronic manufacturing, and power supply system applications.
