(20 µA), a wide input voltage range (0.35 to 5.5V) and low start-up voltage (0.65V). The MCP1640 is available in SOT-23-6 and 2x3mm-8 DFN packages. This chapter provides an overview of the MCP1640 Boost Controller Evaluation Board and covers the following topics: •... -
Page 10: What The Mcp1640 Synchronous Boost Converter Evaluation Board Includes
MCP1640 Synchronous Boost Converter Evaluation Board User’s Guide An enable (EN Switch selection) is used to enable and disable the MCP1640. When enabled, the MCP1640 will regulate the output voltage; when disabled, the MCP1640 disconnects the path from input to output for “true-disconnect”. -
Page 11: Chapter 2. Installation And Operation
Li-Polymer batteries in addition to distributed 3.3V to 5.0V applications. The MCP1640 is capable of regulating the output voltage over a wide 2.0V to 5.5V range and typically can deliver over 100 mA of load current at 3.3V output when supplied from a single 1.2V cell. -

2. Set the desired output voltage using the V SEL mini dip switch. 3. Set the enable to the desired state using the EN mini dip switch. 4. When EN is set ON or high, the MCP1640 is enabled and V can be measured on the V and GND terminals. - Page 14 MCP1640 Synchronous Boost Converter Evaluation Board User’s Guide 2.3.1.4 ADJUSTABLE V SETTING The resistor divider RT and RB are used to set the converter output voltage. By setting the V SEL switch in the open or OFF position, the output voltage can be calculated using the following equation: ...
