MCP1640 AAAA Battery Boost Converter Reference Design
The Microchip MCP1640 AAAA Battery Boost Converter Reference Design demonstrates how the MCP1640 Step-Up Converter IC, in conjunction with an 8-bit PIC Microcontroller, can optimise battery life for applications that operate in standby mode for long periods of time. During Standby, the enable signal for the MCP1640 has a low frequency, with less than 1% positive duty cycle. This maintains the output of the MCP1640 device up to 2.3V, which is sufficient to keep the PIC microcontroller live. This solution reduces up to 80% of the No Load Input Current the MCP1640 consumes in PFM Mode.
