Status: In Production
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.
The device integrates a 36V, 400 mΩ low-side switch, which is protected by the 1.8A cycle-by-cycle inductor peak current limit operation. Low-voltage technology allows the MCP1664 to start-up without high inrush current or output overshoot. All compensation and protection circuitry is integrated to minimize the number of external components.
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...
