ON Semi Conduct, the premier supplier of high-performance, energy-efficient silicon solutions for green electronics, further expands its lineup of LED lighting solutions with single-stage integrated power factor correction (PFC) and isolated buck AC-DC (AC-DC) A new off-line LED driver for power conversion - the NCL30001. 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, 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.
The NCL30001 is available in a 16-lead SOIC package and is priced at $1.05 per unit in 10,000-piece quantities.
