The LM3401 is a high-efficiency hysteretic PFET switching controller that provides a high-performance, constant current drive to a string of LEDs, resulting in a constant colour output.
National Semiconductor has added two new light-emitting diode (LED) drivers to its PowerWise range National's LM3401 and LM3405A LED drivers power 1 to 5W, high-brightness LEDs found in industrial and automotive applications as well as general illumination applications such as solid state and signage Each offers a wide input voltage range and provides a constant current to regulate the LED brightness and low feedback voltage to minimise power dissipation
