Input
2–24V
Output
5–28V (adjustable pot)
Current
2A peak (1A continuous)
Efficiency
~93%
// github libraries
// notes & warnings
Set output voltage with the trim pot BEFORE connecting load. Ratings are optimistic — derate ~50% for sustained current. Step-DOWN regulator (LM2596 / MP1584) is cheaper if Vin > Vout.
