MCP1640 Sync Boost Converter Evaluation Board

Part Number: MCP1640EV-SBC

Summary:

This 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

Product Features

    • Input voltage range, VIN: 0.35V to 5.5V, with VIN ≤ VOUT; 1mA load after start-up
    • Fixed output voltage: 2.0V or 3.3V and 3.3V or 5.0V, selected using a mini dip switch on board
    • Output current: typical 100mA @ 3.3V Output, 1.2V Input or 350mA @ 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
    • PWM Switching Frequency = 500 kHz
    • 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)
    • For standby applications operates and consumes only 19μA while operating at no load and provides a true disconnect from input to output while shutdown

Summary

This 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
  • 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”).

Devices Supported: MCP1640
