National Semiconductor has added two new LED drivers to its PowerWise energy-efficient product family. The LM3401 and LM3405A power 1 W to 5 W, 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.
Featuring a voltage range from 4,5 V to 35 V, the highly efficient LM3401 includes a scalable current drive of greater than 3 A and a 100% duty cycle. A low feedback voltage of 0,2 V and accuracy within 3% provide a constant current to provide constant colour output from an LED.
The LM3405A features a voltage range from 3 V to 22 V and is able to regulate from a loosely coupled 12 V a.c. rail found in industrial and commercial lighting applications. The small SOT-23 package allows LEDs to be placed into small-form-factor light bulbs to offer higher efficiency versus the traditional halogen and incandescent sources for illumination.
