Product Description

Power Integrations TOP254GN is a highly integrated flyback converter off liner power switch IC designed for efficient power supply applications. This 8-pin surface mount device supports power ratings up to 30W and maintains stable operation within a temperature range of -40°C to 150°C. Its compact dimensions (9.83mm length, 6.6mm width, 3.68mm height) allow for versatile integration in modern electronic assemblies.

The TOP254GN series offers multi-mode operation to maximize efficiency at all load levels, with no need for additional heatsinks up to 35W, which reduces system complexity and thermal management challenges. It features built-in output overvoltage protection (OVP) and line undervoltage detection (UV) to prevent operational glitches and extend the device’s durability under line surges and faults.

With a switch on resistance of 9.7Ω and operating current of 2.08A, this power switch IC ensures reliable current control and power conversion quality. Its design optimizes line feed-forward compensation to suppress line ripple, resulting in smooth power delivery and reduced interference.

This IC is ideal for industrial, commercial, and consumer electronic power supply designs where compact size, high efficiency, and robust protection are required. Applications include switching power supplies, adapters, and converters serving various electronic equipment and systems.

Highly integrated monolithic off-line switcher for power supplies up to 195 W. Multi-mode efficiency operation across all load conditions. No heatsink required for power outputs up to 35 W. Output overvoltage protection (OVP) enhances safety.

Line undervoltage detection (UV) prevents turn-off glitches. Accurate programmable current limit and soft-start feature reduces stress. Compact 8-pin surface mount package with dimensions optimized for PCB space. The product is manufactured in China and complies with the highest standards to optimize power management in electronic circuits.
