Description
The STCS2 is a Bi CMOS constant current source designed to provide a precise constant current starting from a varying input voltage source. The main target is to replace discrete ponents 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.
