MIKROE LED Driver Click

LED driver Click carries the MCP1662 high-voltage step-up voltage driver from Microchip. The Click is designed to run on either 3.3V or 5V power supply. It communicates with the target microcontroller over PWM pin on the mikroBUS™ line.


The MCP1662 device is a compact, space-efficient, fixed-frequency, non-synchronous step-up converter optimized to drive LED strings with a constant current from a two- or three-cell alkaline or lithium Energizer®, or NiMH/NiCd, or one-cell Lithium-Ion or Li-Polymer batteries.

The device integrates a 36V, 800 mW low-side switch, which is protected by the 1.3A cycle-by-cycle inductor peak current limit operation.


LED driver Click has a power input and a PWM input, so the LED lights can be dimmed. It's a great choice for driving LED strips.
