Evaluation Board for MCP1664 LED Driver
Manufactured By:Microchip
Part Number:ADM00641
The MCP1664 LED Driver Evaluation Board is used to evaluate and demonstrate Microchip Technology’s MCP1664 product. This board demonstrates the MCP1664 in a boost converter application supplied from an external voltage source, which drives a string of LEDs with three selectable currents. The MCP1664 LED Driver Evaluation Board was developed to help engineers reduce the product design cycle time.
The MCP1664 device is a compact, space-efficient, fixed-frequency, non-synchronous step-up converter optimized to drive LED strings with constant current from two and three-cell alkaline and NiMH/NiCd or one-cell Li-Ion or Li-Polymer batteries.
Applications:
- Two and Three-Cell Alkaline or NiMH/NiCd White LED Driver for Backlighting Products
