TOP245GN Description

Short technical summary and product information.

The Power Integrations TOP245GN is part of the TOPSwitch-GX family of integrated offline switchers. This device utilizes a proven topology to cost-effectively integrate a high-voltage power MOSFET, PWM control, and fault protection onto a single CMOS chip.

 

Key electrical specifications include a voltage rating of 700V, a power output of up to 30W, and a switching frequency range of 66kHz to 132kHz. It features a Flyback topology and isolated output, with integrated fault protection for current limiting, over temperature, and over voltage conditions. The device also includes frequency control features.

 

Designed for flexibility and efficiency, the TOP245GN supports various power outputs depending on the input voltage and configuration, such as 19W for 230 VAC adapter applications and 34W for open frame designs. It also offers 15W for 85-265 VAC adapter and 23W for open frame configurations.

 

The TOP245GN is available in a surface mount package, specifically an 8-SMD (7 Leads), Gull Wing configuration (SMD-8B). Its operating temperature range is -40°C to 150°C (TJ).
