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.
Features
Input voltage: One AAAA Alkaline Battery
Output Voltage : 3.3V
Output Current: <130 mA
Up to 75% efficiency
Standby Battery Current: 14.5 μA @ 1.5V Input
Start-Up Voltage: 0.65V at VIN = 1.2V, VOUT = 3.3V and IOUT = 1 mA, Resistive Load
Automatic PFM/PWM Operation
PWM Switching Frequency = 500 kHz
ON/OFF Switch Button, with 25 Seconds ON
LED Status Indication (Output ON and Low Battery)
Battery Holder with Reverse Battery Protection
