【What it does】: The DC-DC step-down converter can step down the voltage of 6-24V to 5V and output a current of up to 3A to meet your project needs.
【New design】: The DC-DC step-down converter uses 3 solid ceramic capacitors (MCC), which are safer and have smaller ripples.And use flat copper inductors to improve conversion efficiency (up to 97.5%).
【Module Protection】: DC-DC Buck Converter with Output Overvoltage Protection, Output Short Circuit Protection, and Input Reverse Polarity Protection.
【Parameters】: input voltage: DC 6-24V; output voltage: 5.1-5.2V; output current: MAX 3A (please strengthen heat dissipation for full load use), the actual test results input 12V output current 2A does not need to strengthen heat dissipation.
【Application】: Widely used in mobile phone charging, car charger (maximum output current 3A, recommended 2.1A for long-term use).
