LN2103 2A / 40V Step-Down LED Driver

LN2103 is a step down LED driver that is designed to meet least 2A continuous output current for high power LED application, and utilizes PWM control scheme that switches with 150KHz fixed frequency. The input voltage range of LN2103 is from 4.2V to 40V. It is suitable for series-parallel 1W, 3W, or 5W high power LED application due to the high operation vol.
