Single-cell boost driver with special features for operation with solar lamps

  • boost current driver for up to 40mA with a direct connection to the solar cells
  • Minimum input voltage 0.9V - allows the use of a single NiMH cell (1.2V)
  • Requires only one inductor, one resistor and a Schottky diode as external components
  • No external photo sensor required (solar cell operates as a light sensor)
  • Adjustable light threshold for switching on the LED
  • Low current consumption
  • Battery deep discharge protection
  • LED solar garden lamps
  • House number and sign lighting with solar cells
  • Solar powered LED road markers
  • Solar pocket torches
  • Model making, toys using solar cells
  • Solar battery chargers
