Extends single stage solutions with high power
factor capability and broadens two stage solutions up to 150
watts
ON Semiconductor (Nasdaq:ONNN), driving energy efficient
innovations, announces two new series of power factor corrected
(PFC) offline Ac-Dc drivers for high performance LED lighting
applications. Extending the NCL3008x family of products, the
NCL30085, NCL30086 and NCL30088 address single stage design
implementations up to 60 watts (W) that require high power factor.
The NCL30030 broadens the existing solutions which support higher
power (up to 150 W) two stage topologies that require low optical
ripple and wide LED forward voltage variation.
“Compact, robust and flexible, these new PFC controllers address
the need for higher performance solutions in the LED lamp and
driver market,” said Shane Chilton, senior director of the Ac-Dc
Power Conversion division at ON Semiconductor. “These solutions
deliver precise current regulation via our unique architecture.
This translates into LED lighting designs that are more flexible
and can be future proofed with a common control approach.”
The NCL30085, NCL30086 and NCL30088 utilize
a power factor corrected current control algorithm which makes them
suitable for flyback buck-boost, and SEPIC topologies. By operating
in quasi-resonant mode these devices are able to deliver optimum
efficiency across wide line and load levels. The innovative control
methodology they employ allows strict current regulation to be
achieved (within 2 percent typically) solely from the primary
side.
The non-dimmable NCL30088 is complemented by the NCL30086, which
is ‘smart-dimmable,’ supporting analog and/or pulse-width
modulation (PWM) dimming with a single input that controls the
average LED current. Completing the series is the NCL30085 which
supports three levels of log step dimming (70 percent, 25 percent
and 5 percent). As a consequence, it permits light output reduction
by toggling the AC switch on/off to signal the controller to lower
the LED current point. All three devices feature user configurable
current thermal fold-back mechanisms that help prevent overheating
and enable manufacturers to support longer lifetime warranties.
The NCL30085 and NCL30088 are offered in SOIC-8 packages, while
the NCL30086 is offered in SOIC-10 package with pricing of the
series starting at $0.35 per unit in 10,000 unit quantities.
The NCL30030 is a two stage PFC controller plus
quasi-resonant flyback controller optimized for medium and high
power LED lighting applications up to 150 W. This device is best
suited for commercial lighting such as lowbay, highbay and
streetlighting. The NCL30030 makes use of a proprietary multiplier
architecture to achieve low harmonic distortion and near-unity
power factor while operating in critical conduction mode (CrM).
The NCL30030 is in an SOIC−16 package with 1 pin removed for
high voltage spacing and pricing starts at $0.65 per unit in 10,000
unit quantities.
