200W LLC Resonant power supply

admin — Tue, 07 Feb 2012 16:23:27 +0000

Magnetica is proud to announce that extensive tests have been performed over the off-the-shelf magnetic components equipping the 48Vdc-130W street-lighting LLC resonant demo board, in order to raise the output power capability up to 200W, yet maintaining full wide input range mains.

By operating the PFC stage topology in Fixed-Off-Time mode (FOT), and further optimizing the LLC resonant stage, it’s now possible to obtain higher power densities, still delivering astounding efficiency and thermal performances.

Transformer and PFC inductor are already stock-available, ready for shipment.

Part numbers are detailed here for your convenience:

Resonant Transformer 04652 : Switch Mode Transformer for full resonant HB converters to be used with L6599 controller. The leakage inductance balancing and the specifically designed coil former make this transformer suitable for high performance applications. An auxiliary winding is present for powering power supply controller.
PFC inductor 04658 : Inductor for Buck, Boost and Buck-Boost Dc/DC converter, available also in half-bridge, push-pull and full-bridge applications.

05677 – Demo Board SMPS Street Light 130W 85-305Vac

admin — Fri, 11 Nov 2011 15:39:42 +0000

Application: LEDs are getting more and more popular thanks to their high efficiency and very long lifetime. So it’s possible to give a strong contribution to reduce the energy consumption for internal or external lighting. This also happens in street lighting applications, where the higher efficiency and lifetime are vital for reducing costs. Therefore this Demo Board is tailored on a 130W 48V LED power supply specification for street lighting.
We have developed two versions in collaboration with ST MICROELECTRONICS.

This is the WIDE INPUT MAINS version(85-305Vac) but is also available the RANGE EUROPEAN INPUT MAINS RANGE version (177-277Vac) cod 5623
