BB Nexgen 400mA

 $9.00 - $11.00 


BB Nexgen 400mA

  • Maximum Vin: 6V or Vout whichever is lower.
  • Maximum Vout: 6V or Vf which ever is lower.
  • Output Regulation: Semi-regulation, Full Constant current regulation. Note1:
  • Open Load Protection: No
  • Output adjustable: Set by two SMT (0603) resistors. See Resistor Calculator
  • Output Current formula: 0.05 / Rsense = Iout
  • Efficiency: 80%~91%
  • Maximum Output: 1A
  • Vin overdrive voltage: Vout+0.7V
  • Tallest Component: 3mm
  • Compatibility: Sandwich, ECan, Aleph Light Engine
  • Diameter: 0.55"
  • Technology: SMT Components top side only, Battery anode pad backside

Note1: Safe mode is ~1.5A input current. If output doesn't go into full regulation it falls back to safe mode. For a Nexgen 750mA or Nexgen 1A, this critical starting voltage is ~3.4V. Input voltages above this will start the regulator into full constant current regulation and it will regulate down to ~2V input. A Nexgen 500mA will almost always start in full regulation mode.
