PTC Launches Medium/Low power LED Lighting Driver IC Series

Erosion in LED lighting product pricing has become a trend that has been matched by growth in the LED lighting market size.  However, further cost reductions in the LED die and thermal-structural-optical system are limited.  Hence, lighting driver IC pricing has become the key factor to enable LED bulb manufacturers to control their cost.  Energy standards in Europe and the U.S. (Energy Star EVP5) have been clearly defined.  Mandatory requirements are that residential lighting drive power factor (PF) must be greater than 0.7 and commercial lighting PF must be greater than 0.9.  PTC provides a high quality-to-price ratio linear driver IC solution, the PT6923A, to satisfy the needs of LED bulb manufacturers for a low cost and high efficiency driver IC.

High-performance driver ICs provide competitive advantages in terms of efficiency, size, reliability, and lifetime for LED bulb manufacturers.  The PT6923A is a Linear Constant Current Controller IC for LED bulb, LED tube lamp, and compact-sized LED lighting applications. Its proprietary 3-segment driving topology improves power factor, THDI, and efficiency and increases PF value to 0.9 or higher.  The PT6923A includes an integrated temperature compensation function that effectively eliminates the flickering problem for abnormal temperature environments.  EMI issues are solved through proprietary technology activated during segment switching.  Few external components are required enabling flexibility in many compact size applications.


In addition to linear driver ICs, PTC also provides several Switching Mode Power Supply solutions.  The PT6979 is a non-isolated Switching Mode Power Supply IC and its green energy technology, the Single-Stage PFC structure, contributes to high PF value (PF > 0.9) and low harmonics (THDI = 15%), which meet the requirements of IEC63000-3-2.  The PT6979 has outstanding line regulation and load regulation and provides several protection functions for AC-DC LED lighting applications.
