ON Semiconductor Introduces New Linear Constant Current Regulators as Cost-Effective Discrete Solution for Regulating Current in LEDs

Two-Terminal Linear Constant Current Regulators Deliver Simple, Economical and
Robust Current Regulation for Automotive, Industrial Signage and Architectural
LED Lighting Applications
PHOENIX--(Business Wire)--
ON Semiconductor (Nasdaq: ONNN), a leading global supplier of high-performance,
energy-efficient silicon solutions, today introduced a new series of
two-terminal linear constant current regulators ideal for driving current in
automotive, industrial signage and architectural LED lighting applications. The
new constant current regulators operate over a wide range of input voltages, and
provide engineers a simple and cost-effective solution for regulating current in
their applications without compromising on performance.

"ON Semiconductor continues to deliver a wide array of LED driving solutions for
a broad range of applications," said Dan Huettl, director and general manager
for ON Semiconductor`s Small Signal Division. "The new constant current
regulator solution does not require any external components, reduces inventory
cost, and offers our customers an extremely simple, economical and yet robust
device to easily incorporate in their lighting designs."

About the Devices

The new series of constant current regulators is based on patent-pending
self-biased transistor technology, and is targeted for a broad range of LED
applications with varying input voltage. By regulating the voltage over the wide
range, the devices ensure constant brightness over the operating voltage range.
The series is designed with a negative temperature coefficient to protect LEDs
from thermal runaway at extreme voltage and operating temperatures.

The NSI45 series of constant current regulators are offered in 20 milliamp (mA),
25 mA and 30 mA device options available in a SOD-123 package and in a SOT-223
package. These devices are available in plus/minus (±)10 percent and (±15)
percent steady state regulated current (Ireg) tolerance. The series is rated at
45 volts (V) with operating temperature range of -40 oC to 85 oC and maximum
junction temperature of 150 oC. The SOD-123 package is 3.7 mm x 1.6 mm x 1.2 mm
surface mount package and can dissipate 230 milliwatts (mW) of power at 85 oC
with 500 mm / 1 ounce copper on the board. The SOT-223 is 7.0 mm x 6.5 mm x 1.6
mm surface mount package, dissipates 630 mW of power at 85 oC with 500 mm / 1
ounce copper on the board and is ideal for extreme thermal operating
environments. The devices are qualified to stringent automotive standard of
AEC101. In addition, these devices are lead-free RoHS compliant and use
halogen-free mold compound.

The NSI45 in SOD-123 package is priced at $0.0545 per unit in 10,000 quantities.
The NSI450 in SOT-223 package is priced at $0.090 per unit in 10,000 quantities.
