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 and the current consumption is reduced to less than 1uA.
