GL7203 3W High Power White LED Driver

The GL7203 is a set-up DC-DC converter that delivers a regulated output current. the device switches at a 1.0MHz contant frequency, allowing for the use of small value external inductor and ceramic capacitors. The GL7203 is targeted to be used for driving loads up to 1A from a two-cell alkaline batt.
