The MCP1640EV-SBC evaluation board uses the MCP1640 in a high-efficiency (up to 96%), fixed frequency (500 kHz), step-up DC-DC converter.

It demonstrates Easy-to-use and minimum number of external components power supply solution for applications powered by one-cell, two-cell, or three-cell alkaline, NiCd/NiMH; one-cell Li-Ion or Li-Polymer batteries. Selection of the best operating mode for efficiency (PWM/PFM), a wide input voltage range (0.35 to 5.5V) and low start-up voltage (0.65V), PCB layouts recommendation for SOT23-6 and 2x3mm-8 DFN packages and three common output voltages to evaluate: 2.0V, 3.3V and 5.0V enable selection (when disabled, the MCP1640 disconnects the path from input to output for “true-disconnect”).

The MCP1640 is a compact, high-efficiency, fixed frequency, step-up DC-DC converter. It provides an easy-to-use power supply solution, with a minimum number of external components for applications powered by one-cell, two-cell, or three-cell alkaline, NiCd, NiMH, one-cell Li-Ion or Li-Polymer batteries.

The MCP1640 automatically selects the best operating mode for efficiency, Pulse Width Modulation (PWM) or Pulse Frequency (PFM); it has a low quiescent current (20 μA), a wide input voltage range (0.35 to 5.5V) and low start-up voltage (0.65V).

The MCP1640 Synchronous Boost Converter Evaluation Board is used to evaluate and demonstrate Microchip Technology’s MCP1640 products. 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.

Key Applications: One, Two and Three Cell Alkaline and NiMH/NiCd Portable Products, Single Cell Li-Ion to 5V Converters, Li Coin Cell Powered Devices, Personal Medical Products, Wireless Sensors, Handheld Instruments, GPS Receivers, Bluetooth Headsets, 3.3V to 5.0V Distributed Power Supply
