The DT3100 is a floating current driver IC for regulating the current flowing through an LED string. The application of DT3100 is configured in series or parallel with an LED string. The DT3100 can work as voltage controlled current source, current regulator, or cut-off. It is suitable for applications adopting periodical AC voltage source. The PCB layout is also very flexible to meet various shape requirements. It is especially suitable for replacing incandescent light bulb and linear type fluorescent lamp. The DT3100 provides the key protection function for short circuit between CS and VS pins to protect the LED string and the DT3100 itself from burning out. The DT3100 is available in SOT-89-3L Package.
