- 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.
