TOP201YN Description

Short technical summary and product information.

The Power Integrations TOP201YN is a highly integrated offline PWM switch designed to simplify power supply designs and reduce component count. It combines a 700V power MOSFET with a PWM controller, oscillator, and protection circuitry in a standard TO-220-3 package.

 

This device supports multiple topologies including Buck, Boost, Flyback, and Forward, offering versatility for various applications. It provides up to 50W of output power with a 67% duty cycle and operates at a frequency of 100kHz. Key features include built-in auto-restart and cycle-by-cycle current limiting for robust fault protection, along with on-chip thermal shutdown.

 

The TOP201YN is suitable for 100/110/230 VAC off-line power supply applications. Its design emphasizes reduced component count, increased efficiency, and improved system reliability, making it a cost-competitive solution compared to discrete designs.

 

Packaged in a through-hole TO-220-3 configuration, the TOP201YN is designed for ease of mounting and integration into existing circuit designs. It operates within a temperature range of -40°C to 150°C (TJ).
