Precise Details Features Adopts new imported chips for enhanced performance. Maximum output current of 3A. Can sustain 2.1A continuously, with sufficient surplus. At 3A, operates for about 20 seconds before activating overheat protection and restarting. Achieves 3A current with adequate cooling. A new design eliminates the need for electrolytic and tantalum capacitors. Utilizes three large solid-state ceramic capacitors (MCC) for high-end circuits, ensuring longer life and safety. Non-isolated DC synchronous rectifier technology ensures high circuit conversion efficiency: 97.5% at 6.5V to 5V 0.7A and 94% at 12V to 5V 1A. Integrated inductance and low internal resistance significantly enhance conversion efficiency, reducing heat generation compared to common shielded inductors. Note For low static current: With a 12V input and 5V output, alongside an LED lamp indicator, the static current remains under 0.45 mA. Can connect directly to car batteries or via cigarette lighter line or ACC power wire. Output configuration allows adjustable and fixed voltage. Fixed output is non-customizable, but can be spot-welded on board. Special voltage adjustments are possible with a potentiometer. Includes LED light indication for convenient voltage output display. Features enabling ports with default low-level shutdown mode for easy control. Compatible as a replacement for 78 series linear regulators, such as 7805 and 7812. Specification Input Voltage: DC 4.5-24V Output Current: 3A Conversion Efficiency: 97.5% Switching Frequency: 500KHz Output Ripple: 20mV Load Adjustment Rate: +1% Voltage Adjustment Rate: 0.5% Dynamic Response Speed: 5% at 200µs Size: 18 x 10 x 3.8 mm Package Included 1 x Mini DC-DC Adjustable Step Down Power Supply
