Microchip | MCP1650EV

MCP1650EV Boost Controller Evaluation Board demonstrates Microchip Technology’s MCP165X Boost Controller product family in two high-power, boost converter applications.

The first application features the MCP1651 (8-pin MSOP) with the low battery detect feature and provides a regulated 5 V output with an input voltage range of 2.8 V to 4.8V. The second application uses the MCP1653 (10-pin MSOP), with both low battery detect and power good features. The input voltage for this application is 3.3 V, with the output boosted to 12V. The high-frequency boost controllers product family consists of four high-frequency, boost-converter devices having different combinations of features.

Features:

• MCP1651 in a boost application configured in Bootstrap mode. This application circuit regulates the output to 5 V while delivering 1 A of current as the input voltage varies from 2.8 V to 4.8 V.
• MCP1653 in a boost application configured in non-Bootstrap mode. This application circuit regulates the output voltage to 12 V while delivering 400 mA of current as the input voltage varies from 3.0 V to 3.6 V.
