Product Description

Power Integrations TOP253EN is a highly integrated high side off liner Power Switch IC packaged in a 7-pin eSIPC format. It features a robust operating current of 1.37A and a power rating of 29W, making it suitable for off-line power supplies up to 195W. The device is surface mount compatible with dimensions 10.24mm length, 8.25mm width, and 2.06mm height, optimized for space-constrained electronic designs.

The IC incorporates critical protections including output overvoltage protection (OVP), line undervoltage (UV) detection to prevent turn-off glitches, and line overvoltage shutdown extending line surge capabilities. Its switch on resistance RdsOn is 15.2Ω, reducing power losses and enhancing efficiency under varying load conditions.

Designed for harsh environments, it operates reliably from -40°C to 150°C. The multi-mode operation significantly maximizes efficiency throughout all load conditions, including standby with no-load consumption minimized. Its compact design often eliminates the need for heat sinks up to 35W, helping reduce system size and cost.

The device supports output overvoltage protection to safeguard connected circuits. Incorporates line undervoltage detection preventing operational glitches. Offers built-in programmable current limiting for operational safety.

Operates efficiently across all load ranges with optimized line feed-forward for ripple rejection. Integrated soft-start minimizes startup stress enhancing device reliability. Suitable for industrial electronics, power management, laboratory instruments, manufacturing, HVAC, and commercial applications.

The TOP253EN series from Power Integrations is an excellent choice for engineers designing power supplies requiring compact, efficient, and safe power switching components.
