MCP1640EV-SBC

MCP1640EV-SBC is a MCP1640 synchronous boost converter evaluation board. This board demonstrates the MCP1640 in two boost-converter applications with multiple output voltages. It can be used to evaluate both package options (SOT-23-6 and 2x3-8 DFN). The MCP1640 synchronous boost converter evaluation board was developed to help engineers reduce the product design cycle time. Three common output voltages can be selected: 2.0V, 3.3V and 5.0V. The output voltage can be changed with a mini-dip switch that changes the external resistor divider. 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”.

• Input voltage range, VIN: 0.35V to 5.5V, with VIN ≤ VOUT; 1mA load after start-up
• Output current: typical 100mA at 3.3V output, 1.2V Input or 350mA at 5.0V output, 3.3V input
• Start-up voltage: 0.65V at VIN = 1.2V, VOUT = 3.3V and IOUT = 1mA, resistive load
• Automatic PFM/PWM operation
• 500kHz PWM switching frequency
• Enable state selectable using mini-dip switch on board
• Peak input current limit up to 800mA
• Over-temperature (if the die temperature exceeds 150°C, 10°C hysteresis)
• Powered by 1-cell, 2-cell, or 3-cell alkaline, NiCd, NiMH, 1-cell Li-Ion or Li-Polymer batteries
