INTRODUCTION
WHAT IS THE MCP1640 SYNCHRONOUS BOOST CONVERTER
EVALUATION BOARD?
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 is available in SOT-23-6 and 2x3mm-8 DFN packages.
This chapter provides an overview of the MCP1640 Boost Controller Evaluation Board
and covers the following topics:
• What is the MCP1640 Synchronous Boost Converter Evaluation Board?
• Contents of the MCP1640 Synchronous Boost Converter Evaluation Board
FIGURE 1-1:
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.
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.
