Boost LED Regulator Evaluation Board


The MCP1643 Synchronous Boost LED Constant Current Regulator Evaluation Board is developed to help design engineers reduce the product design cycle time. The evaluation board demonstrates the MCP1643 in a boost converter application supplied by one AA battery (one-cell alkaline, NiCD or NiMH), or from an external voltage source, which drives an LED with three selectable currents. Output currents of 25, 50, 75 and 100mA can be selected.

Start-up voltage: 0.65V

Mechanical battery reverse polarity protection

Thermal shutdown at 150°C with +25°C hysteresis

Input voltage range, VIN: 0.35V to 2.5V, with VIN < VOUT

PWM Switching Frequency: 1 MHz

Enable state selectable using mini-dip switch on board

1.6A Peak Input Current Limit

Over-temperature Protection (if the die temperature exceeds 150°C, 25°C hysteresis)
