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 HV9803 is a LED driver IC with average-mode constant current control and operates in a constant off-time mode. It can be powered from a 7.0 – 13.2 V supply. The device is equipped with a current ...

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 ...

Predicting simpler designs, the CL320, CL325, and CL330 LED drivers provide three channels of constant current output, capable of powering three LED strings at currents of 20 mA, 25 mA, and 30 mA each ...

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 ...
