On February 25, 2010, ON Semiconductor, the premier supplier of high-performance, energy-efficient silicon solutions for green electronics, introduced a new power factor correction (PFC) dimmable light-emitting diode (LED) driver – NCL30000 for residential and commercial lighting applications.
Typical applications include LED driver power supplies, LED downlights, triac TRIAC dimmable LEDs, and power factor corrected constant voltage power supplies. This device is compatible with leading edge TRIAC dimmers and trailing edge transistor dimmers. Depending on the dimmer used, the LED output can be adjusted down to 2%.
The company offers three 15 watt (W) reference designs designed to drive 4 to 15 LEDs at 350 milliamps (mA). They can also be easily adjusted to match power levels from 5 W to 30 W:
× NCL30000LED1GEVB: 115 Vac version, 90 to 135 Vac input line voltage (TRIAC dimming)
× NCL30000LED2GEVB: 230 Vac version, 180 to 265 Vac (TRIAC dimming)
× NCL30000LED3GEVB: Extended Universal Edition, 90 to 305 Vac
The NCL30000 operates over the -40°C to +125°C temperature range, ensuring the wide range of environmental operating conditions specified in most solid-state lighting (SSL) applications. The NCL30000 has a low startup current of typically 24 microamperes (μ; A) and a low operating current of typically 2 mA for an energy efficient design.
Other key features of the NCL30000 include programmable on-time limiters, zero-current sense (ZCD) sensing modules, gate drivers, and all other pulse width modulation (PWM) circuits and protection features required to apply CrM switching power supplies. The NCL30000 is ON Semiconductor's fully tested GreenPoint® for off-line, high power factor TRIAC dimming LED drivers; key components in the reference design for US ENERGY STAR commercial and residential lighting applications. Documentation for this reference design and other reference designs above is available on the ON Semiconductor website.
Zheng Zhaoxiong, senior director of global sales and marketing for ON Semiconductor's power and portable products, said: "Our customers need dimmable LED driver solutions that are compatible with wiring and control. The NCL30000 offers excellent dimming performance with dimming down to 2% This device is ideal for isolated flyback applications, but can also be used for non-isolated buck topologies."
Package and price
The NCL30000 is a lead-free, halogen-free and brominated flame retardant (BFR) device that is RoHS compliant and is available in an 8-lead SOIC package. The unit price is $0.45 per 10,000-piece lot. Samples are now available. The current expected production lead time is 8 to 12 weeks after the order is received (ARO-automatic revolving purchase).
