Overview
The MCP1642B/D High-Current Synchronous Boost Converter Evaluation Board is used to evaluate and demonstrate Microchip’s MCP1642B/D products. The board can be used to evaluate both package options (MSOP-8 and 2 x 3 mm DFN-8). The MCP1642B/D is capable of regulating the output voltage over 1.8V to 5.5V range and typically can deliver over 400 mA of load current at 3.3V output when supplied from a single 1.5V cell. The Evaluation Board was developed to help engineers reduce the product design cycle time.
- Start-up voltage: 0.65V at VOUT = 3.3V and IOUT = 1mA, resistive load
- Input voltage range after start-up, VIN: 0.35V up to VOUT – 200-300 mV recommended headroom
- Adjustable output voltage range: 1.8V to 5.5V, set by a resistor divider on board (bottom application using MCP1642B-ADJ)
- Fixed 3.3V output voltage (using the fixed output voltage MCP1642D-33)
- Output current: typical 200 mA @ 3.3V Output, 1.2V Input or 800 mA @ 5.0V Output, 3V Input
- Output Disconnect (MCP1642B)
- Input-Output Bypass (MCP1642D)
- PWM Operation
- PWM Switching Frequency = 1 MHz
- Enable state, Power Good, Switch test points on board
- Peak Input Current Limit of 1.8A
- Overtemperature protection (if the die temperature exceeds +150°C, +35°C hysteresis)
- 1 x MCP1642 High Current Boost Converter (ADM00460)
