single stage LED driverCirrus Logic, Inc. has introduced a first family of single-stage LED drivers, the CS1615/16, targeting the incandescent lamp replacement market. Through patented technology, the CS1615/16 consistently outperforms competing single-stage LED drivers in dimmer compatibility while offering a total bill-of-material cost equal to competing solutions, according to the company.  Across a broad range of dimmers, the company asserts the CS1615/16 consistently dims to nearly zero light output, which closely matches the dimming performance of incandescent light bulbs. Patented dimmer-compatibility technology identifies the type of dimmer in use and applies the appropriate operating mode. This adaptive digital technology consistently provides full functionality on even the most challenging leading edge, trailing edge and “smart” digital dimmers. The LED drivers enable next-generation bulbs to meet proposed standards from Energy Star, NEMA, California Energy Commission and other standards. The CS1615/16 provides primary-side constant current control and tight LED current regulation, high efficiency, active power factor correction and low THD. These ICs support isolated and non-isolated topologies with minimal EMI filter design requirements.
