by Keith Szolusha
Schottky in 16-Pin MSOP
Introduction
As the number of applications for
medium power (1WвЂ“4W) LED strings
grows, so does the need for compact, efficient, high performance LED drivers.
The LT3519 LED driver satisfies the
needs of a wide variety of applications,
including LCD displays, automotive
and avionic applications, architectural and industrial lighting, portable
projection and scanners. ItвЂ™s 16-pin
MSOP package includes accurate LED
current regulation, small size, high
efficiency, PWM and analog dimming
for brightness control and open circuit
protection with fault detect. Easy Layout: Integrated
Power Switch, Compensation
Components and Schottky The 400kHz LT3519 LED driver features an integrated 750mA 45V peak
power switch, integrated compensation components and an integrated
low leakage Schottky diode, making
designs simple and small. Despite …
