Description

The MCP1664 LED Driver Evaluation Board is used to evaluate and demonstrate Microchip Technology’s MCP1664 product. This board demonstrates the MCP1664 in boost-converter application supplied from an external voltage source, which drives astring of LEDs with three selectable currents. The MCP1664 LED Driver EvaluationBoard was developed to help engineers reduce the product design cycle time.

Features

  • input voltage range, VIN: 2.4V to 5.5V, with VIN VOUT
  • Undervoltage lockout: 2.3V to start; 1.85V to stop
  • Adjustable output current: 90 mA, 180 mA or 270 mA, selected using a mini dipswitch on board
  • PWM Switching frequency = 500 kHz
  • Variable resistor and triangular wave generator on the board that can be used forPWM dimming
  • 1.8A peak current limit
  • Overtemperature protection (if the die temperature exceeds +150°C, 25°C hysteresis)
  • Open load protection: if the LED string fails or is disconnected, the converter willshut down to prevent failure.
