Evaluation Board for MCP1663 9V/12V/24V Output Boost Regulator
The MCP1663 Evaluation Board is used to evaluate and demonstrate Microchip Technology’s MCP1663 step-up switching regulator. This board comes with two distinct applications. The 1st circuit can be used to evaluate the MCP1663 in the typical boost configuration 9V/12V selectable output. The board also provides an example of how a higher input voltage application can be implemented.
The MCP1663 device is a compact, high-efficiency, fixed-frequency, non-synchronous step-up DC-DC converter which integrates a 36V, 400 mΩ NMOS switch. It provides a space-efficient high-voltage step-up power supply solution for applications powered by either two-cell or three-cell alkaline, Ultimate Lithium, NiCd, NiMH, one-cell Li-Ion or Li-Polymer batteries.
Applications:
- Two and Three-Cell Alkaline, Lithium Ultimate and NiMH/NiCd Portable Products
- Single-Cell Li-Ion to 5V, 12V or 24V Converters
- LCD Bias Supply for Portable Applications
- Camera Phone Flash
- Portable Medical Equipment
- Hand-Held Instruments
