鈻?/div>
Supplying LEDs with constant current for
varying input voltages
Low voltage lighting
Small appliance LED lighting
Car LED lights
The current is set with external resistor up to 1.5
A with a 鹵10% precision; a dedicated pin allows
implementing PWM dimming.
An open-drain pin output provides information on
load disconnection condition.
Description
The STCS1 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.
