STEVAL-ILL014V1 Datasheet, PDF (1/4 Pages) STMicroelectronics – Evaluation board for the STCS1 constant current controller for high brightness LEDs

STEVAL-ILL014V1
Features
Evaluation board for the STCS1 constant current
controller for high brightness LEDs
Data Brief
■ Input voltage (V_IN): 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
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 STCS1
constant current LED driver. The STCS1 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.
