Description

  • STCS1ADEMO1, STCS1 Demo Board is designed to supply a high power LEDs under the severe conditions of automotive and industrial applications resulting in constant brightness and extended LED life-time. The STCS1 is a BiCMOS constant current controller designed to provide a precise constant current starting from a variable input voltage source. The STCS1 is well suited for applications requiring high voltage input and it is able to withstand automotive load-dump events up to 40V. An external shunt resistor in the ground path of the connected LEDs is used to sense the LED current

Key Features

  • Input Voltage
    4.5 to 40 V
  • Output Current
    0.5 A
