24V Buck Module 3A
Size: 18.2 (Long) * 10.3 (WIDE) * 3.8 (High) mm
1: The use of new original American imports of chips.
2: 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.
3: 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.
4: 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%.
5: The use of integrated inductor, ultra-low internal resistance, maximize the conversion efficiency. Lower calorific value, higher efficiency, lower than ordinary shielding inductance.
6: Ultra Small volume, 18 (long) $number (wide) * 3.8 (high) mm, Mini.
7: 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.
8: 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.
9: The output with LED light indicator, convenient and intuitive indication of voltage output.
10: With the enabling port, the default mode of work, low level shutdown, to facilitate the control
11: Can be used to replace 78 series of linear regulators, such as 7805 7812 and so on.
