Step-down module 3A 12v 24v to 5V 3.3V 9V 3A fixed voltage mini DC Adjustable Buck module

24V Buck Module 3A

Size: 18.2 (Long) * 10.3 (WIDE) * 3.8 (High) mm

The use of new original American imports of chips.
Output current maximum 3 A, long time running 2.1A, ample allowance. 3 A runs 20 seconds or so chips into the overheat protection reboot, which can be worked on by cooling the chip on the 3 A current.
The use of a new design, circuit design does not require electrolytic capacitors and tantalum capacitors (electrolytic capacitor life is short, tantalum capacitor explosion risk). Use of the current high-end circuit on the large size of solid-state ceramic Capacitor (MCC) 3.
The use of non-isolated DC synchronous rectification, circuit conversion efficiency is very high, in 6.5V to 5V 0.7A when the efficiency of $number. $number, 12V to 5V 1 A also reached 94%.
The use of integrated inductor, ultra-low internal resistance, maximize the conversion efficiency. Lower calorific value, higher efficiency, lower than ordinary shielding inductance.
Ultra Small volume, 18 (long) $number (wide) * 3.8 (high) mm, Mini.
Ultra-low static current, 12V input, output 5V voltage, LED lamp led case-static current less than 0.45 ma. The connection in the car battery no need to add a switch, can be connected to the cigarette line, or ACC power cord.
Output integration can reconcile fixed voltage, fixed output is not required to customize, directly on the board spot welding, special voltage can be adjusted with potentiometer, very strong versatility.
The output with LED light indicator, convenient and intuitive indication of voltage output.
With the enabling port, the default mode of work, low level shutdown, to facilitate the control
Can be used to replace 78 series of linear regulators, such as 7805 7812 and so on.
