MCP1640 Boost Converter Evaluation Board

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

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)
