TOP246YN Description

Short technical summary and product information.

The Power Integrations TOP246YN is part of the TOPSwitch-GX family of integrated offline switchers. This device effectively combines a high-voltage power MOSFET, PWM control, and fault protection circuitry onto a single CMOS chip, simplifying system design and reducing costs.

 

Key electrical specifications include an operating voltage of 700V, a maximum output power of 125W, and a switching frequency range of 66kHz to 132kHz. It features a duty cycle of 66.5% and includes fault protection for current limiting, over temperature, and over voltage conditions. The device operates within a temperature range of -40°C to 150°C (TJ).

 

Packaged in a TO-220-7C configuration with through-hole mounting, the TOP246YN is suitable for various power supply designs. Its topology is flyback, and it provides isolated output. The integrated nature of the switch simplifies external component requirements and enhances design flexibility. The device also offers frequency control features.

 

This component is designed for applications requiring efficient and reliable AC-to-DC conversion. Its integrated features and robust protection mechanisms make it a versatile choice for power management solutions.
