3W High Power White LED ME2206 Ver04 3W High Power White LED ME2206 General Descriptionÿ 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 ...
