1.1 Variants
LED-Warrior05 is available in standard variants for
200mA and 350mA output current. The 200mA
variant is a low current ripple version optimized
for driving OLED with <1% Ipp.
Input and output connections are available with the
following options:
Input crimp, output crimp
Input crimp, output plug
Input crimp, output solder
Input solder, output solder
1.2 Custom variants
Custom output current versions are available on
request. Output connectors can be modified.
Thermally conductive adhesive pad for mounting
can be added. Minimum order quantities may
apply.
2. Functional overview
LED-Warrior05 is a point-of-load regulator for
LED lighting applications. By providing a highly
efficient constant current regulation off a DC
source LED-Warrior05 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
Dimensions in mm
Height at thickest point: 6.5mm
Tolerances:
Outer contour: ±0.2mm
When mounting on a conductive surface make sure
to add spacers or an insulating layer under the
module to avoid short circuits
3.1 Crimp Connectors
The crimp connectors used on the LW05 require a
special crimping tool. Crimping tools can be
pruchased separately.
The connectors are of the AVX/ELCO 00 9175
family. Wires with insulation diameter 0.7 to 1mm
fit into the connectors.
3.2 SMD Mounting
LW05 may be mounted as a SMD part. For details
please contact our support.

3.3 Pin Descriptions
Vin
Supply voltage positive input. Apply a DC voltage
of 7V to 30V here. The input is protected with a
fuse and a diode to prevent damage from reversed
power supply and safely disconnect the power in
case of a failure.
GND
Supply voltage negative input and ground
reference for MOD input.
LEDa
Positive output for LED, connect the anode of the
first LED of the string to this pin.
LEDk
Negative output for LED, connect the cathode of
the last LED of the string to this pin. This pin is not
identical to GND!
MOD
PWM input. Pulling this pin high shuts off the
output. Feeding a PWM signal with up to 1kHz can
be used to control the brightness of the connected
LEDs. Pulling the pin high permanetly puts LW05
in a standby mode. This pin can be left
unconnected if no brightness control is required.
4. Connecting the LEDs
The maximum number of LEDs that can be driven
by LED-Warrior05 depends on the supply voltage
and the combined forward voltage of the LEDs.
Input voltage needs to be about 2.5V higher than
the total forward voltage of the LED string for
proper operation.
4.1 Reducing output ripple
To reduce output ripple and possibly reduce EMC
problems a capacitor may be put parallel to the
LEDs, preferably connected direct between LEDa
and LEDk of the LED-Warrior05.
The 200mA low ripple version already has such a
capacitor installed on the module to optimise it for
use with OLED.
4.2 EMC
LED-Warrior05 has been designed to produce a
minimal level of EM emissions.
As a component LED-Warrior05 can not be EMC
approved. It has been tested in the configuration of
our AgniLine product and passed with comfortable
margin.
