TOP253PN Description

Short technical summary and product information.

The Power Integrations TOP253PN is an advanced integrated offline switcher belonging to the TOPSwitch-HX family. Designed for flyback topology, this component is suitable for various power supply applications.

 

Key electrical specifications include a breakdown voltage of 700V and a switching frequency of 66kHz, with an option for 132kHz. It supports a maximum duty cycle of 78% and can deliver up to 25W of output power. The device operates within a wide input voltage range from 85V to 265V AC and features fault protection including current limiting, over temperature, and over voltage.

 

Packaged in an 8-DIP (0.300", 7.62mm) with 7 leads, the TOP253PN is designed for through-hole mounting. Its operating temperature range is -40°C to 150°C (TJ). The integrated switch simplifies design and reduces component count.

 

This device offers features like multi-mode operation for efficiency, programmable output overvoltage protection, and improved auto-restart for fault conditions. It is suitable for applications requiring reliable and efficient power conversion.
