STCS2

2 A max constant current LED driver

Features

■ Up to 40 V input voltage

■ Less than 0.5 V voltage overhead

■ Up to 2 A output current

■ PWM dimming pin

■ Shutdown pin

■ LED disconnection diagnostic

Applications

■ LED constant current supplying for varying

input voltages

■ Low voltage lighting

■ Small appliances LED lighting

■ Car LED lights

Description

The STCS2 is a BiCMOS constant current source

designed to provide a precise constant current

starting from a varying input voltage source. The

main target is to replace discrete components

solution for driving LEDs in low voltage

applications such as 5 V, 12 V or 24 V giving

benefits in terms of precision, integration and

reliability.

The current is set with external resistor up to 2 A

with a ± 10 % precision; a dedicated pin allows

implementing PWM dimming.

An open-drain pin output provides information on

load disconnection condition.
