Checking for live stock

The Power Integrations TOP256EN is an integrated offline switcher IC designed for flyback‑topology power supplies, combining a high‑voltage MOSFET with control and protection features in one package. It supports universal AC input (85–265 VAC), accommodates up to ~119 W open‑frame or ~60 W enclosed output at 230 VAC input, and operates at switching frequencies up to 132 kHz. The device is part of the TOPSwitch‑HX family and enables compact, efficient designs for consumer, industrial and lighting applications requiring reliable isolated power.

Core Capabilities of the Power Integrations Converter Offline Flyback Topology

Universal input range (85–265 VAC) supports global power systems.
Integrated 700 V-rated MOSFET and controller reduces component count and board space.
High output power capability: up to ~119 W open‑frame at 230 VAC input.
Multi‑mode operation and frequency jittering optimise efficiency and minimise EMI.
Comprehensive fault protection: overvoltage, undervoltage, overtemperature and auto‑restart features.

Engineered for Compact and Efficient Power Conversion

The TOP256EN is designed to simplify power‑supply design with its monolithic architecture and advanced feature set. The integrated MOSFET and control circuitry reduce external component count and PCB footprint. Its protection mechanisms deliver robust operation in demanding environments, supporting product reliability and safety compliance.

Usage Recommendations of the Converter

Design of isolated power supplies for consumer electronics such as set‑top boxes, monitors and laptop adapters.
Industrial control and automation power modules.
LED lighting drivers or ballast circuits.
Medical, telecom or instrumentation power systems.
High‑density power modules and adapters.
