Microsemi Corp. has made a foray into the power conversion and light management market for solid-state lighting fixtures with announcement of a new product. The new power supply module supports 5 to 16 LEDs and provides 90 per cent power conversion peak efficiency while delivering non-flickering dimming down to 10 per cent. Its universal input voltage range is from 90Vac to 305Vac for 50Hz and 60Hz systems.

"The SSL market is a key new market for Microsemi, and we are well-positioned to leverage our leadership in power conversion and light management as well as our analogue mixed-signal design capabilities to develop optimised products for the next-generation of smart lighting fixtures," said Irene Signorino, Microsemi's director of marketing, lighting and automotive products.

The AC/DC power supply and driver are key components in LED fixtures. They need to accommodate LEDs' unique electrical, photometric and thermal behaviour to achieve the promised long life and high energy efficiency. The drivers can perfectly tune and also provide optimised and personalized light via light intensity and light colour controls.

Microsemi's LXMG221W-0700034-D0 module can be integrated into dimming and non-dimming fixtures and meets requirements for both commercial and residential applications, including its pending CE and UL1310 certification. Its compact, IP66-rated plastic package protects the power supply from dust and temporary water exposure and offers a thru-hole for more secure mounting.

Microsemi's principal markets include defence/aerospace and satellite. The company is a supplier of high-reliability discrete components to military and aerospace customers.

The LXMG221W-0700034-D0 is in pre-production with single samples available at Rs.2,771 ($60).
