Facilitate highly repeatable bulb performance and reduced component
count
SAN JOSE, Calif.--(BUSINESS WIRE)--
Power
Integrations (Nasdaq: POWI),
the leader in high-efficiency, high-reliability LED-driver ICs, today
announced its LYTSwitch™-2
family of isolated LED drivers. The new IC family, which delivers up to
12 watts of accurately controlled output power, substantially reduces
component count, resulting in simpler, smaller, more reliable LED
lighting designs.
LYTSwitch-2
LED-driver ICs use primary-side control, resulting in cost-effective,
single-sided PCBs with low component counts. In addition, driver
isolation allows the LEDs to be affixed directly to a metal heat sink,
avoiding the added expense of an electrically isolating enclosure that
is often required for non-isolated drivers. Accurate constant-current
(CC) output tolerance across temperature (better than +/-5% at both
low-line and high-line voltages) reduces the need to over-design systems
in order to meet requirements such as the U.S. ENERGY STAR®
minimum-lumens-delivered specification. Designs using LYTSwitch-2
ICs are also highly efficient – up to 90% in typical applications.
LYTSwitch-2
ICs protect the LED load from surges in line voltage, increasing bulb
lifetime in regions where the mains voltage is subject to frequent
peaks. The constant-current and constant-voltage (CC/CV) control
function maintains a constant voltage on the output of the driver during
no-load operation, preventing damage to the output filter or shutting
down the driver when being tested or installed with no LED string
connected.
Comments
Andrew Smith
, product marketing manager for Power
Integrations: “LYTSwitch-2
LED-driver ICs can be used as a platform to create products from 1 W to
12 W, and they are ideal for low-cost bulbs, ballasts, down-lights and
tubes. Because of the IC’s stability and closely controlled part-to-part
variation, engineers can be confident that their designs will be
repeatable and manufacturable with little or no performance variation.”
LYTSwitch-2
LED-driver ICs feature over-temperature, over-current and open
feedback-loop protection and are simple to design in using Power
Integrations’ PI
Expert design software. Devices are packaged in small,
cost-efficient SO-8 packages as well as MSOP and eSIP packages for
efficient thermal transfer in higher-power applications. LYTSwitch-2
IC pricing starts at 0.52 for SO-8 devices in 10K quantities.
