LвЂ‰DESIGN FEATURES Efficient 48V Buck Mode
LED Driver Delivers 50mA
by Mohammad J. Navabi Introduction
LEDs are efficient, compact and durable, and thus they are replacing
other more traditional light sources
in a variety of applications. One such
application is signage. LEDs save
energy, take less space and need less
maintenance than other sign solutions, such as neon, incandescent or
fluorescent lighting.
LEDs require proper drivers to perform at their peak. A simple DC/DC
converter is not quite enough. It must
convert an input voltage to the LED
string voltage, but it must do it at constant output current. It must also be
able to dim the LEDs by adjusting the
current applied to the LED string. Buck Mode
Constant Current LED Driver The LT3590 is a high voltage current
mode buck mode LED driver capable of
providing a constant current to an LED
string of up to 40V total voltage. It fea-tures internal compensation, an
internal 55V power switch and an
internal 55V Schottky diode (see
Figure 1). The part can deliver up to …
