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 ...

The LED driver automatically adjusts the output voltage to keep the output current constant and therefore the light output constant. This works with a single LED or with a chain of string of LEDs ...

The HV9961, an average-mode, constant-control LED driver IC designed to drive LEDs using a buck topology, is well-suited for a variety of solid-state lighting applications. The HV9961 provides current ...

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 ...
