Just Released: LED Streetlight Design (DER-212)
PI recently released a new engineering report (DER-212) describing a 92%-efficient power supply for LED streetlight applications. The design utilizes Power Integrations' HiperPLC™ power supply controller, which enables a simple, cost-effective circuit design by combining power factor correction (PFC) and resonant (LLC) control functions on a single integrated circuit.
