ON Semiconductor's new offline LED driver NCL30001 performance characteristics

ON Semiconductor has further expanded its lineup of LED lighting solutions with the introduction of the NCL30001, a new off-line LED driver with single-stage integrated power factor correction (PFC) and isolated step-down AC-DC power conversion. This device saves dedicated PFC boost sections, reduces component count, reduces solution cost, and improves overall energy efficiency of LED power systems for applications such as LED street lights, low ceiling lights, wall packs, and building lighting.

Operating in continuous conduction mode (CCM), the NCL30001 can be configured as a constant current driver or a fixed output voltage driver, making it ideal for designs with power requirements from 40 W to 150 W. The controller is available in a SOIC-16 package and operates from 20 kHz to 250 kHz. The multi-function latch pin features an overtemperature shutdown circuit that provides circuit designers with a high degree of flexibility.

Other specifications of the NCL30001 controller include high voltage start-up circuitry, voltage feedforward for improved loop response, input undervoltage detection, internal overload timer, latch input, and high precision multipliers that reduce input line harmonics. ON Semiconductor also offers an isolated single-segment power factor correction LED driver evaluation board for applications requiring direct current output from 40 W to 100 W power range. The current can be adjusted from 0.7 A to 1.5 A for a wider range of high power, high brightness LEDs.

Christophe Warin, AC-DC business unit manager at ON Semiconductor, said: "With the increasing popularity and rapid increase in LED-based lighting design in the marketplace, the need for energy-efficient, cost-effective integrated system management devices is even better. The NCL30001 is fully compatible. These requirements provide engineers with flexible single-segment topology LED drivers that are ideally suited for their new LED lighting products. This is another powerful example of ON Semiconductor's ongoing development of lighting solutions tailored to customer needs."
