1.1 Variants

LED-Warrior01 is available in variants for 350mA,

700mA and 1A output current.

1.2 Custom variants

Custom output current versions are available on

request. Minimum order quantities may apply.

2. Functional overview

LED-Warrior01 is a point-of-load regulator for

LED lighting applications. By providing a highly

efficient constant current regulation off a DC

source LED-Warrior01 is perfectly suited for

applications that require low DC levels for safety

reasons, driving multiple LED groups in one

luminaire, mobile or in-vehicle lighting, and to

refit existing low voltage halogen installations.

3. Mechanical dimensions and connections

Dimensions in mm

Height at thickest point: 7mm

Mounting holes are 2.5mm in diameter.

Solder pad holes are 0.9mm in diameter.

Tolerances:

Hole diameters: -0.05 / +0.1mm

Hole positions: ±0.05mm

Outer contour: ±0.2mm

When mounting the module make sure to use

insulating washers or use screw heads that are

small enough to avoid contact to the surrounding

PCB traces and components. When mounting on a

conductive surface make sure to add spacers or an

insulating layer under the module to avoind short

circuits

GND Supply voltage negative reference for MOD input. input and ground LEDa Positive output for LED, connect the anode of the first LED of the string to this pin. 5. Brightness control The MOD input allows analog or PWM brightness control of the LEDs. By applying a 0.3V-2.5V level to the MOD input the output current can be controlled between 25% to 200% of the nominal value.
