Product details

MCP16251 and MCP1640B Synchronous Boost Converters Evaluation Board

The Evaluation Board for the MCP16251 and MCP1640B Synchronous Boost Converters is used to demonstrate Microchip Technology’s products:
MCP16251, Low Quiescent Current, PFM/PWM Synchronous Boost Regulator with True Output Disconnect and
MCP1640B, 0.65V Start-up Synchronous Boost Regulator with True Output Disconnect.
This board demonstrates the MCP16251/MCP1640B in two boost-converter applications with multiple output voltages. It can be used to evaluate both package options (SOT-23-6 and 2x3mm (T)DFN8). The MCP16251 and MCP1640B Synchronous Boost Converters 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. A switch connected to the EN pin is used to enable and disable the converters. When enabled, the MCP16251/MCP1640B will regulate the output voltage; when disabled, the MCP16251/MCP1640B disconnects the path from input to output for “true-disconnect”.

It can be powered by one-cell, two-cell, or three-cell alkaline, NiCd, NiMH, one-cell Li-Ion or Li-Polymer batteries
Input voltage range (VIN): 0.35V to 5.5V, with VIN ≤ VOUT
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 125mA @ 3.3V Output, 1.5V Input or 200mA @ 5V Output, 3V Input
Start-up voltage: 0.82V (for MCP16251’s Converter) or 0.65V (for MCP1640B’s Converter) at VOUT = 3.3V and IOUT= 1mA, resistive load
Automatic PFM/PWM Operation for the MCP16251 Converter
PWM Switching Frequency = 500kHz
Enable state, selectable using the mini-dip switch on board
Peak Input Current Limit (800mA for MCP1640 or 650mA for MCP16251)
Over-temperature Protection
