Consider the lowly wall wart power adapter. It finds use in millions of electronics devices as a cost- and power-efficient ac-dc voltage-regulated power supply. In effect, designers of electronics ...
Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...
Typical uses today include backlighting for LCD TVs, projectors, computer displays, camera flashes, and vehicle brake lights. All need constant-current LED drivers that are economical and offer high ...
LT3478 and LT3478-1, two 40V, 4.5A dc-dc converters designed to drive high-current LEDs at constant current. Their 2.8V to 36V input range suits them for a variety of applications, including ...
