Power
Integrations (Nasdaq: POWI),
the leader in high-efficiency, high-reliability LED-driver ICs, today
added devices optimized for high-line applications, completing the
roll-out of its LYTSwitch™-4
LED-driver IC family. LYTSwitch-4
ICs deliver accurate output current and high efficiency for bulb and
tube applications and high-bay lighting. The devices simplify design and
reduce cost while ensuring that lamps deliver uniform light output and
provide exceptional performance in TRIAC-dimmable applications.
LYTSwitch-4
ICs feature a combined PFC and CC single-stage converter topology
resulting in a power factor greater than 0.95 and efficiencies of over
90% in typical applications. Designs based on the new drivers easily
meet EN61000-3-2C regulations for total harmonic distortion (THD);
optimized designs deliver less than 10% THD. Regulation is better than
+/- 5% across load and production spread, reducing the need for
over-design to meet minimum luminance targets, cutting system cost. The
devices’ high switching frequency (132 kHz) enables smaller, lower-cost
magnetics to be used, and frequency jittering reduces EMI filtering
requirements. These factors enable LED-driver designs to fit easily into
space-restricted bulb styles.
Comments Andrew Smith, senior product marketing manager for Power
Integrations: “LYTSwitch-4
LED-driver ICs have proven very popular since the initial launch of the
low-line parts, due to a combination of efficiency and excellent dimming
performance. Even when used with leading-edge and trailing-edge TRIAC
dimmers, and at low conduction angles, designs comply with NEMA SSL-7.
Start-up is very fast, typically less than 500 ms, even when dimmed to
less than 10% light output, and pop-on is virtually eliminated.”
Designers can evaluate the new LYTSwitch-4
LED-driver IC family using a new high-line LED lighting
reference design that has been co-developed with Cree. DER-396
describes a PAR38 spotlight LED driver design. These documents and all
other similar reference designs with Cree are hosted at http://www.powerint.com/ledrivers/cree.
LYTSwitch
ICs enable small, longer-lasting lamps in a wide range of applications
including consumer bulbs, commercial lighting and T8 tubes, industrial,
high-bay and exterior lighting. LYTSwitch
devices also offer all the usual safety features common to Power
Integrations products, including over-voltage, over-current and
over-temperature protection. In addition LYTSwitch
devices do not need an optocoupler or electrolytic bulk capacitors,
reducing component count and increasing reliability. High-line LYTSwitch-4
ICs are sampling now in eSIP-7C (E) and eSIP-7F (L) packages, priced
from $0.58 (non-dimming) to $0.62 (dimming) in 10,000-piece quantities.
