STEVAL-ILL014V1
Evaluation board for the STCS1A constant current controller for
high brightness LEDs
Data brief
Features
Input voltage (VIN): 4.5 V to 40 V
Less than 0.5 V voltage overhead
Up to 1.5 A output current
PWM dimming pin
Shutdown pin
LED disconnection diagnostic
RoHS compliant
Description
The best way to power LEDs is to control the
forward current in order to achieve good
matching of light output. LED manufacturers
specify the characteristics (such as lumens,
beam pattern, color) of their devices at a
specified forward current. The STEVAL-ILL014V1
evaluation board demonstrates the operation of
the STCS1A constant current LED driver. The
STCS1A is capable of controlling the LED current
under several application conditions, while also
providing useful features that make it suitable for
different applications such as advertising signs,
automotive interior and exterior lighting, and
emergency vehicle warning lights.
