PI Expert Suite 9.0 design software gives LED lighting design a boost

Power Integrations latest version of its power supply design software, PI Expert Suite 9.0, now includes support for its LinkSwitch-PL and LinkSwitch-PH LED-driver ICs and its recently introduced TinySwitch-4 off-line switcher IC family. Version 9.0 includes an enhanced schematics-manipulation tool and enables designers to upload the resulting BOM from the auto-generated schematic layout to selected, leading design-fulfillment distributors.

The PI Expert Suite 9.0 can help to improve the productivity of power supply design teams by reducing the time to first prototype and by cutting the number of prototype iterations required to reach a finished product. The software now includes support for solid-state-lighting products, enabling LED designs to be optimised for CC, dimming and harmonic emissions.

As with previous-generations, PI Expert Suite 9.0 generates a complete schematic of the power supply and offers power transformer optimisation techniques, even specifying the transformer design and offering links to wound component manufacturers. A heatsink calculation tool also provides the designer with an estimation of the thermal design requirements for a new power supply which may be used to guide layout and mechanical prototyping decisions – avoiding iterations and wasted time.

Enhanced PCB layout recommendations based on the IC device and package chosen allow the designer to minimise trace-induced EMI and board area, and also maximize electrical noise immunity and surge tolerance.

Commenting Peter Vaughan, director of applications engineering at Power Integrations, said “LED-lighting engineers face difficult electrical, mechanical and thermal challenges as they continue to develop innovative solid-state-lighting products. PI Expert remains the only comprehensive PSU design tool capable of satisfying the demands of both experienced and new power supply designers alike. With support for our LinkSwitch-PL and LinkSwitch-PH ICs, they can achieve a better, more efficient solution in a shorter time.”
