3W High Power White LED ME2206

3W High Power White LED ME2206
General Description
Features
The ME2206 is a set-up DC-DC converter
that delivers a regulated output current. The
device switches at a 1MHz constant
frequency,allowing for the use of small value
external inductor and ceramic capacitors.
The ME2206 is targeted to be used for
driving loads up to 1A from a two-cell alkaline
battery. The LED current can be programmed
by the external current sense resistor, Rs,
connected between the feedback pin (FB) and
ground. A low 95mV feedback voltage reduces
the power loss in the Rs for better efficiency.
During the shutdown mode, the feedback
resistor Rs and the load are completely
disconnected and the current consumption is
reduced to less than 1uA.
