Power Integrations.jpgPower Integrations has released an 92% efficient LED streetlight power supply reference design, reports our Technology Editor Steve Bush. For streetlights up to 150W, the supply has a fixed output voltage of 48V at up to 3.125A.

Central to the circuit is the firm's HiperPLC chip, aimed at converters between 80 and 600W, which combines power factor correction (PFC) and a resonant (LLC, inductor inductor capacitor) down converter on the same die.
"The IC provides up to 0.99 power factor and features synchronisation of PFC and LLC controllers," said the firm. "Synchronisation reduces the ripple in the bulk capacitors, which reduces capacitor operating temperature and significantly extends the life of the power supply."

He has worked through the company from Toolmaking to starting the company on the road of LED optics business some 6-7 years ago, starting with a standard range and more in line with the business of custom optics. In between all this he has worked in engineering and as a works Director for a hydraulics company but kept getting pulled back to the optics industrial. We are able to offer the full solution from idea to parts so have a very good understanding on what is needed. You will see some posts from our design team also under my name.
