DC-DC step-up/step-down voltage regulator module with an adjustable output voltage range of 9 V – 30 V and an input voltage range of 2.9 V – 32 V. The circuit automatically boosts or lowers the input voltage, allowing it to power devices even when the supply voltage fluctuates significantly. The regulator can deliver up to 2 A output current, with a typical efficiency of 80–90%, and features an ENABLE pin for low-power operation. Pololu 2573
