(UVLO Start), and the operating input voltage ranges up to 5.5V. For standby applications, MCP1663 can be turned off by pulling the EN pin to GND. The device will stop switching and will consume 300 nA of input current. Note that, while in Shutdown mode, the input voltage will be bypassed to the output through the inductor and the Schottky diode. -
Page 8: What Is The Mcp1663 Mini-Module Sepic Converter Evaluation Board
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), as shown in Figure 1-2. -
Page 9: What The Mcp1663 Mini-Module Sepic Converter Evaluation Board Kit Contains
FIGURE 1-2: MCP1663 Mini-Module SEPIC Converter Evaluation Board. The MCP1663 Mini-Module SEPIC Converter Evaluation Board was developed to help engineers reduce the product design cycle time. 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. -
Page 10: Chapter 2. Installation And Operation
MCP1663 can regulate the output voltage up to 32V and can deliver 250 mA load at 3.3V input and 12V output. At light loads, MCP1663 skips pulses to keep the output ripple low. -
Page 11: Getting Started
GETTING STARTED The MCP1663 Mini-Module SEPIC Converter Evaluation Board is fully assembled and tested to evaluate the MCP1663 product and demonstrate its capabilities. This board requires the use of external laboratory power supplies and load. The mini-module’s performance was tested using a motherboard which includes a... - Page 12 Soldered pads are available in order to allow connecting a load. The peak current limit of the MCP1663 will provide a safe maximum current value. The maximum output cur- rent for the converter will vary with the input voltage, as shown in Figure 2-1.
