REFERENCE DESIGN KIT CONTENTS
FIGURE 1-1:
The MCP1640 Single Quadruple-A Battery Boost Converter Reference Design is
designed to demonstrate the MCP1640 features in a microcontroller application that
optimizes the battery lifetime. The MCP1640 Single Quadruple-A Battery Boost
Converter Reference Design was developed to help engineers reduce product design
cycle time.
At 1.5V input and 3.3V output, the board is capable of 130 mA load current.
The EN signal is used to enable and disable the MCP1640 device. When enabled, the
MCP1640 will regulate the output voltage. When disabled, the MCP1640 disconnects
the path from the input to output for True Output Disconnect Shutdown option. The
MCP1640 Single Quadruple-A Battery Boost Converter Reference Design uses this
feature to reduce no load Standby current. During Standby, the enable signal has a low
frequency, with less than 1% positive duty cycle. This board demonstrates that this
solution increases the battery life.
