Buck Converter Step Down Module LM2596 DC to DC Voltage Regulator, to Power Supply Module, Pack of 2
Advantage DC-DC BUCK POWER module buck 3A The regulator exceeds the efficiency (up to 92%). Output voltage Output voltage range, dc 1.25V to 35V voltage continuously adjustable. Output current Maximum output current 3A. (Note This is a step-down module, the input voltage must be higher than the output voltage. If the output current is greater than 3A, or the output power is greater than 10W, you need to add a heatsinks.) Input voltage Measured 12V input, 5V output current 1A load adjustment rate is less than 1%. Warn This is a
