Power Integrations High Side Off Liner Power Switch IC 8-Pin DIP-C 25W 1.37A TOP253PN

Power Integrations TOP253PN is a high side, off liner power switch integrated circuit (IC) designed as a highly integrated monolithic off-line switcher for use in power supplies up to 195 W. Featuring a DIP-C 8-pin through-hole package, this IC allows for efficient power management with a power rating of 25 watts and an operating current of 1.37 amps.

This device excels in providing high efficiency across all load conditions, utilizing multi-mode operation to optimize performance and reduce no-load consumption during standby. The TOP253PN requires no heatsink for power levels up to 35 W, or up to 48 W at 230 VAC using specific package types, contributing to compact and cost-effective designs.

Enhanced protection features include output overvoltage protection (OVP), line undervoltage (UV) detection to prevent turn-off glitches, and line overvoltage shutdown to extend tolerance to line surges. It incorporates an accurate and programmable current limit and a fully integrated soft-start for minimizing electrical stress during startup phases. Optimized line feed-forward circuitry significantly improves line ripple rejection.

Operating in a wide temperature range of -40°C to 150°C, the TOP253PN is suitable for demanding industrial, commercial, and laboratory power supply applications. The device's compact dimensions (9.83 mm length, 6.6 mm width, and 3.68 mm height) and the through-hole mounting make it convenient for PCB integration.

Typical use cases include power supply circuits in consumer electronics, industrial power management systems, and embedded systems requiring efficient power switching with robust protection. The robust design and protection features make it ideal for environments requiring reliable and efficient power regulation without thermal management complications.
