This compact (0.4? × 0.5?) switching step-down (or buck) voltage regulator takes input voltages between 4 V and 50 V and efficiently reduces them to 3.3 V while allowing for a maximum output current of 600 mA. The pins have a 0.1? spacing, making this board compatible with standard solderless breadboards and perfboards.

Details:

  • Input voltage: 4 V to 50 V (minimum input subject to dropout voltage considerations for currents over 400 mA; see the dropout voltage section for details)
  • Output voltage: 3.3 V with 4% accuracy
  • Maximum output current: 600 mA (see the maximum continuous output current graph below)
  • Fixed 2.1 MHz switching frequency
  • High-voltage enable input can put the board into a low-power state where it draws less than 2 ?A (typical)
  • Low quiescent current: < 0.1 mA (see the quiescent current graph below)
  • Integrated over-temperature and over-current shutoff
  • Small size: 0.5? × 0.4? × 0.1? (13 mm × 10 mm × 3 mm)
  • Weight: 0.5 g
