Flexible platform delivers high PF, low THD and highly accurate
constant-current regulation
SAN JOSE, Calif.--(BUSINESS WIRE)--
Power Integrations (Nasdaq:POWI),
the leader in high-efficiency, high-reliability LED driver ICs, today
announced its LYTSwitch™-5 single-stage LED driver IC family.
LYTSwitch-5 devices combine PFC and constant-current output, and support
multiple common LED driver topologies.

Solid-state lighting applications have highly variable driver
requirements, and power engineers are often challenged to develop
optimized designs quickly in response to requests from lighting
designers. The LYTSwitch-5
family supports the safety-rated isolated flyback topology for ballast
applications, and non-isolated topologies such as buck and buck-boost
for low-cost lamps and bulbs. Additionally, a choice of low-side or
high-side switching enables designers to optimize for low EMI or for
reduced inductor complexity. By achieving over 90% efficiency, 0.9 PF,
less than 5% THD and +/-3% current regulation accuracy over line, load,
production variance, temperature and multiple topologies, LYTSwitch-5 is
the best LED driver for solid-state lighting applications below 25 W.
The high efficiency of LYTSwitch-5
LED driver designs results in smaller heatsinks, more compact
implementations and increased lifetime. Highly accurate CC regulation
reduces the degree of overdesign required to guarantee compliance to
lumen output standards from regulatory bodies such as the California
Energy Commission (CEC) and ENERGY STAR®. 650 V and 725 V MOSFET options
are available to optimize surge-withstand performance for a variety of
product types and geographical installations.
Comments Hubertus Notohamiprodjo, product marketing director at Power
Integrations: “LYTSwitch-5
ICs suit multiple applications including tubes, down-lights and high-
and low-bay ballasts. The simple designs and low component count enabled
by these new ICs result in compact, reliable, high-performance driver
circuits and a platform-based design approach with increased
manufacturing throughput.”
LYTSwitch-5
LED driver ICs offer up to 25 W, an extended universal input range (90 -
308 VAC) and wide output voltage range (2:1). Protection features
include thermal foldback with end-stop shutdown, short-circuit
protection, input and output OVP, overcurrent protection and safe
brown-in and brown-out.
LYTSwitch-5
IC samples are available now. Devices are priced at $0.46 in
10,000-piece quantities. A reference design, DER-515, is available for
download now from the Power Integrations website at www.power.com/lytswitch-5.
