to operate as a constant-current source and is ideal for
driving LEDs. The LT3496 works in buck, boost or buckboost mode. The LT3496 uses a fixed frequency, current
mode architecture resulting in stable operation over a
wide range of supply and output voltages. A frequency
adjust pin allows the user to program switching frequency
between 330kHz and 2.1MHz to optimize efficiency and
external component size. n The LT3496 supports 3000:1 dimming control on each
channel. Each of the three regulators is independently …
