FEATURES
GETTING STARTED
The MCP1640 Evaluation Board offers both package types in two boost-converter
applications for 2.0V, 3.3V and 5.0V output voltage options that can be selected using
a mini dip switch. The enable input is controlled in both boost converter applications
using a mini dip switch.
The MCP1640 Synchronous Boost Converter Evaluation Board has the following
features:
• It can be powered by one-cell, two-cell, or three-cell alkaline, NiCd, NiMH,
• Input voltage range, V
• Fixed output voltage: 2.0V or 3.3V and 3.3V or 5.0V, selected using a mini dip
• Output current: typical 100 mA @ 3.3V Output, 1.2V Input or 300 mA @ 5.0V
• Start-up voltage: 0.65V at V
• Automatic PFM/PWM Operation
• PWM Switching Frequency = 500 kHz
• Enable state selectable using mini-dip switch on board
• Peak Input Current Limit
• Overtemperature (if the die temperature exceeds 150°C, 10°C hysteresis)
The MCP1640 Synchronous Boost Converter Evaluation Board is fully assembled and
tested to evaluate and demonstrate the MCP1640 products. This board requires the
use of external lab supplies and load.

2.3.1.1
Soldered test points are available for input voltage connections. The maximum input
voltage should not exceed 6.0V. The output voltage will not remain in regulation for
input voltages that are greater than or equal to the output voltage.
The MC1640 Synchronous Boost Converter Evaluation Board has two independent
circuit applications, one using the MCP1640 SOT-23-6 package, while the other one
uses the MCP1640 DFN-8 package. The SOT-23-6 package has two output voltage
settings (2.0V and 3.3V) selectable by an on board mini-dip switch. The DFN-8
package has two output voltage settings (3.3V and 5.0V) also selectable by an on
board mini-dip switch.
Soldered test points are available to connect a load. The MCP1640 switch peak current
limit will provide a safe maximum current value. The maximum output current for the
MCP1640 will vary with input and output voltages; refer to the MCP1640 datasheet for
more information on the maximum output current. As an example, the MCP1640 can
typically supply a 3.3V load with 100 mA with a 1.2V input.
