In harsh industrial, automotive and military applications, systems must operate reliably through severe overvoltage events. 

The LTC ® 4366’s adjustable floating topology is capable of extremely high voltages; the operational upper voltage is limited 

only by MOSFET ratings. During high voltage transient events, the LTC4366 clamps the output to a user-defined voltage, 

while the fault timer ensures safe shutdown of the MOSFET if the fault persists.

APPLICATION NOTES 

Design Considerations for LED Lighting Applications 

Introduction 

Lighting applications have grown dramatically from those supporting 

status indicators on front panels to a wide range of general and special 

purpose illumination applications. LEDs, due to their high reliability, low 

power, low heat output, precise and long lifetime lighting characteristics 

are rapidly replacing older lighting technologies. 

Designing lighting applications, using LEDs, is more involved than 

fi nding the latest and greatest LED. LED lighting systems are comprised of 

multiple subsystems: LEDs, LED drivers, thermal management, and optics-

Micron Product Longevity Program 

Micron’s PLP is designed to provide stable memory architectures for 

long-life applications like those in automotive, industrial, medical, 

and aerospace. Through PLP we make a range of DRAM, NAND, and 

NOR devices available for a minimum of 10 years. 

Applications with extended life cycles face a challenge as the components designed appear to 

go through constant change; whether from obsolescence, process shrinks, new features and even 

industry consolidation. This adds up as you spend time, resources and dollars long after the product 

has entered production. 

Recognizing this need for product longevity Micron introduced the Product Longevity Program 

for select DRAM, NAND and NOR memory devices available for a minimum of 10 years.

LTC5585 - Wideband IQ 

Demodulator with IIP2 and DC 

Offset Control 

The LTC®5585 is a direct conversion quadrature demodulator optimized for high linearity 

receiver applications in the 700MHz to 3GHz frequency range. It is also usable in the 400MHz to 

700MHz and 3GHz to 4GHz ranges with reduced performance. It is suitable for communications 

receivers where an RF signal is directly converted into I and Q baseband signals with bandwidth 

of 530MHz or higher. The LTC5585 incorporates balanced I and Q mixers, LO buffer amplifi ers 

and a precision, high frequency quadrature phase shifter. The integrated on-

LTC3600 - 15V, 1.5A 

Synchronous Rail-to-Rail Single 

Resistor Step-Down Regulator 

The LTC3600 is a high effi ciency, monolithic synchronous buck regulator whose 

output is programmed with just one external resistor. The accurate internally generated 

50μA current source on the ISET pin allows the use of a single external resistor to 

program an output voltage that ranges from 0V to 0.5V below VIN. The VOUT voltage feeds 

directly back to the error amplifi er in unity gain fashion and equals the ISET voltage. 

The operating supply voltage range is 4V to 15V, making it suitable for dual lithium-

XL375 CC - 260 Watts without Fans 

Convection Cooling Option Delivers 260 Watts Without Fans 

The new Convection Cooling Option for the XL375 family delivers 260 watts 

across all output voltages and eliminates the fans and fan controllers needed to cool 

conventional power supplies, saving cost and freeing up valuable component space. 

Doing away with fans and related components and circuitry is significant to designers 

tasked with increasing the MTBF and decreasing the noise of products (fans may fail, and 

they generate most of the audible sound in contemporary designs).

Portal is a quarterly publication containing new products, technologies 

and development tools available from Nu Horizons leading suppliers. 

Portal is availabe both in print and on the web. Sign up online to receive 

your copy, be notifi ed of upcoming issues or to request samples of the 

products found inside. 

LabCam delivers online training opportunities in a way that recognizes 

the value of engineers’ time. As easily as You Tube® videos, engineers 

can quickly load and watch videos from industry leaders consisting of 

insights on products, evaluation kit overviews, end-user applications 

and more. Each tutorial is up to ten minutes in length and features 

technology experts, CEOs and/or peers introducing new solutions 

or explaining integral aspects of an important product, solution or 

application. This free value-added program is packaged for short, 

informative and high quality distance learning. 

Nu Horizons is proud to present our education and training program, 

which offers engineers the opportunity to participate in technical 

seminars conducted by experts focused on the latest technologies 

from our leading suppliers. This program provides higher velocity 

learning to help minimize start-up time to quickly begin your design 

process utilizing the latest development tools, software and products. 

Check online for the latest seminar schedule. 

In order to simplify the design process, Nu Horizons has created a series 

of application notes designed to guide engineers through the process 

of interfacing different devices together. Using a detailed step-by-step 

approach, these design guides identify key elements in the design 

process. Topics in the application notes are organized by design task 

and each topic is a stand-alone section, with a short introduction or 

overview, followed by the step-by-step design guidelines. All steps 

include a suffi cient level of detail to provide the designer with relevant 

information to proceed quickly and easily from start to fi nish. 

Nu Horizons offers a wide range of development / evaluation boards, 

tools and kits featuring the latest technology from the most trusted 

suppliers in the industry. Visit the development tool section of our 

website for a variety of solutions all aimed at providing a low-cost 

solution for designers to accelerate a product’s time-to-market.
