|
| 9 | +- VO+: Output |
|
| 10 | +- GND: Common Ground |
|
| 11 | +- IN+ Input |
|
| 12 | +- EN: Enable |

|
| 14 | +Tuning |
|
| 15 | + |
|
| 16 | +- The default output is adjustable. |
|
| 17 | +- If you need to fix the output voltage, use a knife to cut off the connection in the red circle, and then use solder to connect the pad at the voltage position you need· |
|
| 18 | + |
|
| 19 | +## Features |
|
| 20 | + |
|
| 21 | +- Use brand new original chips imported from the United States, definitely not domestic chips, disassembled chips. |
|
| 22 | +- The output current should not be greater than 3A, 2.1A for long-term operation, and the margin is sufficient. |
|
| 23 | +- Using a new scheme design |
|
| 24 | + - the circuit design does not require electrolytic capacitors and tantalum capacitors (electrolytic capacitors have a short life, and tantalum capacitors have the risk of explosion). |
|
| 25 | + - 2 large-size solid ceramic capacitors (MCC) used in high-end circuits are used. |
|
| 26 | +- The new solution uses synchronous rectification, and the circuit conversion efficiency is very high. |
|
| 27 | + - When converting 6.5V to 5V 0.7A, the efficiency is as high as 97.5%. |
|
| 28 | + - When converting 12v to 5V IA, it also reaches 94%. |
|
| 29 | + - Unlike some peers, the efficiency is only 60.70. %. (The efficiency test removes the voltage drop of the input reverse protection diode and fuse). |
|
| 30 | +- Use high-current shielded inductor and ultra-low internal resistance to improve conversion efficiency. Reduce calorific value. |
|
| 31 | +- Small size, 20 (length) * 11 (width) * 5 (height) mm, |
|
| 32 | +- Low quiescent current, quiescent current 0.85 mA. No need to add a switch when connecting to the car battery, it can be connected to the cigarette lighter cord or ACC power cord. |
|
| 33 | +- The output integrates adjustable and fixed voltages. The fixed output does not need to be customized. |
|
| 34 | + - It can be spot welded directly on the board. |
|
| 35 | + - It is very suitable for voltage and can be adjusted with a potentiometer. |
|
| 36 | + - It is very versatile. |
|
| 37 | +- Integrated enable port, the default is the working mode, low level is turned off, which brings convenience to control |
|
| 38 | +- Can be used to replace 78 series linear regulators, such as 7805, 7812, etc. |

|
| 54 | +- Conversion efficiency: up to 97.5% (6.5 to 5V0·7A) |
|
| 55 | + |
|
| 56 | + |
|
| 57 | +- Switching frequency: 500KHz |
|
| 58 | +- Output ripple: about 20mV (12v to 5V3A) 20M bandwidth |
|
| 59 | +- Working temperature: industrial grade G40℃ to +85℃) (the higher the ambient temperature, the smaller the output power) |
