General Description
The MAX1916 low-dropout bias supply for white LEDs
is a high-performance alternative to the simple ballast
resistors used in conventional white LED designs. The
MAX1916 uses a single resistor to set the bias current
for three LEDs, which are matched to 0.3%. The
MAX1916 consumes only 40μA of supply current when
enabled and 0.05μA when disabled.
The MAX1916’s advantages over ballast resistors
include significantly better LED-to-LED bias matching,
much lower bias variation with supply voltage variation,
significantly lower dropout voltage, and in some appli-
cations, significantly improved efficiency. The MAX1916
requires a 200mV dropout at a 9mA load on each out-
put to match the LED brightness.
The MAX1916 is available in a space-saving 6-pin Thin
SOT23 package.
