TOP250Y Description

Short technical summary and product information.

The Power Integrations TOP250Y is part of the TOPSwitch-GX family of integrated offline switchers. This device cost-effectively integrates a high-voltage power MOSFET, PWM control, and fault protection onto a single CMOS chip.

 

Key features include a 132 kHz switching frequency, which is automatically reduced at light loads for high standby efficiency. It offers extremely low consumption in remote off mode, with typical values of 80 mW at 110 VAC and 160 mW at 230 VAC. The device supports up to 19W of output power in adapter configurations at 230 VAC.

 

Designed for flexibility and efficiency, the TOPSwitch-GX family integrates functions to reduce system cost and improve performance. It includes features like soft-start, frequency jittering for lower EMI, and hysteretic thermal shutdown for automatic fault recovery. The Y/R/F packages also offer a half frequency option for video applications.

 

This component is suitable for various AC-DC power supply designs where efficiency and cost-effectiveness are critical. Its integrated nature simplifies board design and reduces the need for external components.
