ADM01014

ADM01014 is a MCP1663 3.3V, 300mA SEPIC DDPAK mini-module evaluation board used to evaluate the MCP1663 SEPIC converter. This board demonstrates the capabilities of the MCP1663 SEPIC converter, which has its O/P voltage set to 3.3V and is designed in a very small form factor (DDPAK package). The size plays an important role in every application where space is constraints. This 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. The EN pin is a logic-level input and will enable the regulator’s output when its voltage is greater than 85% of VIN. When this pin is set low or connected to ground, the SEPIC converter enters Output Disconnect mode. In this application, the output voltage is set to the proper value by using an external resistor divider, resulting in a simple and compact solution.
