Description
- The LM3401MM is a hysteretic PFET Controller for high power LED drive, designed to provide constant current to high power LEDs. The LM3401 drives an external P-MOSFET switch for step-down (buck) regulators. The LED driver delivers constant current within ±6% accuracy to a wide variety and number of series connected LEDs. Output current is adjusted with an external current sensing resistor to drive high power LEDs in excess of 1A. For improved accuracy and efficiency, this LEDS driver features dual-side hysteresis, very low reference voltage and short propagation delay. A cycle by cycle current limit provides protection against over-current and short circuit failures. Additional features include adjustable hysteresis and a CMOS compatible input pin for PWM dimming.
- Hysteretic control for speed and simplicity
- Programmable current limit
- Input UVLO
- No output capacitor required
- This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
