TOP247YN Description

Short technical summary and product information.

The TOP247YN from POWER is an Off-Line Converter that integrates a high-voltage power MOSFET, PWM control, and fault protection onto a single CMOS chip. This design reduces system cost and improves performance and energy efficiency.

Key features include an extended power range for higher power applications and no heatsink requirement up to 34 W using P/G packages. It offers fully integrated soft-start for minimum stress and overshoot, and an externally programmable accurate current limit. The device provides line sensing for OV/UV detection and line feed-forward with DCMAX reduction.

All package types include transparent features like 132 kHz switching frequency (automatically reduced at light load), frequency jittering for lower EMI, wider DCMAX, and hysteretic thermal shutdown for automatic fault recovery. A half frequency option is available in Y/R/F packages for video applications. The TOP247YN regulates to zero load without requiring a dummy load, simplifying design and optimizing system cost.

This component is suitable for various power supply designs where efficiency, cost-effectiveness, and integrated protection features are critical. Its design flexibility and performance enhancements make it a valuable choice for engineers.
