MIKROE-2807

LED driver 2 click board™ carries the MCP1643 LED constant current regulator. It is a compact, high efficiency, fixed frequency, synchronous step-up converter, optimized to drive one LED with the constant current. It can be powered by a two-cell alkaline/NiMH/NiCd battery (2.4V) or via the mikroBUS™ power supply pins, also features 3W high power LED by QT-Brightek. This integrated circuit is perfectly suited for high brightness/power LED applications: portable LED lighting products, LED Flashlight and Head Lamps, Rechargeable Flashlights, General LED constant current applications and so on.
