PART NUMBER: VLD24-XXX

DESCRIPTION: constant current dc-dc converter

applications

features

The VLD24-XXX series is a step-down

constant current source designed for

driving high power LEDs. The available

output currents are: 300mA, 350mA,

500mA, 600mA, 700mA. Despite its

compact size, the VLD24-XXX series is fully

featured with very high efficiency, wide

input voltage range, high ambient operating

temperature, and two means of LED dim-

ming: PWM digital dimming and analog

dimming control, via a trim POT.

• power LED driver

• high efficiency up to 95%

• wide input voltage range

• constant current output

• PWM digital dimming

• short-circuit protection

• analog dimming

• output on/off control
