The MCP1663 device is a compact, high-efficiency, fixed-frequency, non-synchronous step-up DC-DCconverter 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, Lithium, NiCd, NiMH, one-cell Li-Ion or Li-Polymer batteries.

| The MCP1663 Mini-Module SEPIC Converter Evaluation Board is used to evaluate Microchip Technology’s MCP1663 product. This board demonstrates the capabilities of the MCP1663 SEPIC converter, which has its output voltage set to 3.3V and is designed in a very small form factor (DDPAK package.
Another important feature of this evaluation board is that it has the EN pin accessible and can be controlled from an MCU or another device.
|
| The MCP1663 USB programmable power supply reference design is intended to highlight the versatility of the MCP1663 boost regulator configured in a SEPIC topology while also demonstrating inter-functionality between a broad range of analog and digital Microchip devices in a programmable power supply application example.
|
| 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.
