8. Absolute maximum ratings

Input Voltage (Vin relative to GND): -0.3V to +30V (40V for 0.5sec)

MOD pin input voltage (realtive to GND): -0.3V to +6V

Input Current: 1.25A

Operating temperature:

LW01-350: -30°C to +85°C in still air

LW01-700: -30°C to +85°C in still air

LW01-1000: -30°C to +65°C in still air

Absolute maximum ratings must not be exceeded or permanent damage to the LED-Warrior01 may

result.

8.1 Thermal precautions

When operating at elevated ambient temperature,

vertical mounting in an air volume sufficiently

large to allow convection is recommended to

reduce surface temperature of the regulator.

Additional cooling measures can help to further

reduce the regulator temperature and increase long

term reliability.

No part of the module surface may exceed 125°C

during operation at any time.

8.2 Electrical Characteristics

Input Voltage (Vin): 7V to 30V

Standby current (MOD grounded): 20μA to 40μA

Output current (tested parameter):

LW01-350: 348mA ±20%

LW01-700: 699mA ±10%

LW01-1000: 1000mA ±10%

8.3 Failure modes

The most common failure mode seen when the

regulator is destroyed due to overtemperature or

overcurrent is a short circuit between Vin and

GND.

Overvoltage typically also leads to a short circuit

between Vin and GND, additionally the LEDs can

be exposed to overvoltage in this case.

8.4 Recommended safety measures

An appropriate fuse or other current limiting

measure in the power supply is required to prevent

fire hazards in case of malfunctions.

Materials with low flash points must be kept away

from the regulator. The surface temperature of

parts of the regulator may reach up to 125°C

surface temperature when used at elevated ambient

temperatures and maximum power.
