The MCP1653 is a 750 kHz gated oscillator boost controller packaged in an 8 or 10-pin MSOP package. Developed for high-power, portable applications, the gated oscillator controller can deliver 5 watts of power to the load while consuming only 120 µA of quiescent current at no load. The MCP1653 can operate over a wide input voltage range (2.0V to 5.5V) to accommodate multiple primary-cell and singlecell Li-Ion battery-powered applications, in addition to 2.8V, 3.3V and 5.0V regulated input voltages.
The MCP1650 SEPIC Power Supply Demo Board is used to evaluate Microchip’s MCP1650 boost controller in a low power application that requires a regulated output voltage from an input source that can be greater than, less than, or equal to the output voltage. As provided, the MCP1650 SEPIC Power Supply Demo Board generates a 5.0V output from a 3.0V to 7.0V source.
The MCP1650 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 5V output with an input voltage range of 2.8V to 4.8V. The second application uses the MCP1653 (10-pin...
