TOP258PN Description

Short technical summary and product information.

The Power Integrations TOP258PN is an integrated offline switcher IC from the TOPSwitch-HX family. It is designed for flyback applications and features a voltage rating of 700V and a power output of up to 48W. The device operates at a frequency of 66kHz and includes fault protection for current limiting, over temperature, and over voltage.

 

This component utilizes a Through Hole mounting type and comes in an 8-DIP package with 7 leads. The operating temperature range is from -40°C to 150°C (TJ). The TOPSwitch-HX family offers enhanced EcoSmart features, multi-mode operation for efficiency, and low thermal impedance.

 

Key features include user-programmable output overvoltage protection, line undervoltage detection, and an accurate programmable current limit. The device also incorporates frequency jittering to reduce EMI filter costs and improved auto-restart for fault conditions.
