CamSemi C3183 offers low cost, flexible approach for LED lamps to 20 W

ENGLAND: CamSemi has announced a new high performance LED driver IC that will provide manufacturers with greater design flexibility in their drive to develop lower cost, more energy-efficient A-series, GU10 and other space-constrained LED lamp types.

The new C3183 LED driver IC targets volume applications in a wide power range from 3 to 20 W and with the same part being suitable for both high and low line applications (230 or 110 V), unlike many competitive approaches requiring multiple parts.

C3183 uses recent advances in CamSemi’s patented Primary Side Sensing (PSS) and power-saving technologies to boost system performance and energy efficiency, while eliminating significant costs versus alternative solutions.

This new LED driver IC delivers a power factor of 0.7 without needing a high voltage input electrolytic capacitor which saves cost but also increases lifetime of the overall system.  Use of quasi-resonant switching and other techniques enable operating efficiencies in excess of 90 percent and C3183 provides current regulation at a new ‘best in class’ level of +/- 3 percent allowing more margin for thermal design.
