Overview
The MCP1664 LED Driver Evaluation Board is used to evaluate and demonstrate Microchip Technology’s MCP1664 product. This board demonstrates the MCP1664 in a boost converter application supplied from an external voltage source, which drives a string of LEDs with three selectable currents. The MCP1664 LED Driver Evaluation Board was developed to help engineers reduce the product design cycle time.
- Input Voltage range (V IN ): 2.4V to 5.5V, with VIN < V OUT
- Undervoltage Lockout: 2.3V to Start; 1.85V to Stop
- Adjustable Output Current: 90 mA, 180 mA or 270 mA, selected using a dual switch on-board
- PWM Dimming using PWM generator on board
- PWM Switching Frequency: 500 kHz
- 1.8A Peak Input Current Limit
- Overtemperature Protection (if the die temperature exceeds +150°C, with 15°C hysteresis)
- Open Load Protection in case of: LED fail or FB disconnected/fault
- 1x MCP1664 LED Driver Evaluation Board (ADM00641)
