The new national semiconductor high brightness LED driver with temperature control function of management

Recently, National Semiconductor Corporation Ns (National Semiconductor Corporation) has launched a new temperature management control function LED driver LM3424, and launched online design corresponding support tools.

This LM3424 chip 20 pin TSSOP package cooling capacity, can drive high brightness LED as many as 18 series, the application condition of typical output drive current of more than 2A. This chip can provide voltage regulator for Buck, boost, SEPIC, flyback and buck / buck topology and other applications. The LM3424 chip is suitable for a wide input voltage range from 4.5V to 75V, and the built-in pulse width modulation (PWM) controller can support high speed operation. For example, the product can support up to 2.0MHz frequency synchronization oscillator. In addition, the function of the chip also includes PWM dimming and analog dimming, programmable soft start and low power, thermal shutdown and a variety of different types of protection, such as the term flow.
