Note:
1、The above is only a list of typical products. If you need products beyond the list, please contact our sales. 2、The maximum capacitive load indicates the maximum capacitive load that + VO or - vo can be connected to,If the value is exceeded, the product will not start normally..
Typical Application Circuits
1. Standard Application:
If further reduction of input and output ripple is required, a capacitor filtering network can be connected at the input and output terminals, and the application circuit is shown in Figure 1. However, attention should be paid to selecting appropriate filtering capacitors. If the capacitance is too large, it is likely to cause startup problems. For each output, while ensuring safe and reliable operation, the recommended capacitive load values are detailed in Table 1
| Vin (vdc) | Cin(uF) | Vo(Vdc) | Cout(uF) |
| 3.3/5 | 4.7 | 3.3/5 | 10 |
| 12 | 2.2 | 9 | 4.7 |
| 15 | 2.2 | 12 | 2.2 |
| 24 | 1 | 15 | 1 |
| 24 | 1 |
Table 1 Recommended capacitive load values for details
2. EMC typical application:
| Vin (Vdc) | 3.3/5/12/15/24 |
| C1/C2 | 4.7uF/50V |
| C3 | See the cout of Table 1 |
| LDM | 4.7uH |
| CY | 270pF/2KVDC |

3. Notes：Output Load Requirements
In order to ensure that the module can work efficiently and reliably, the minimum output load should not be less than 10% of the rated load.If the power you need is really small, please connect a resistor in parallel between the positive and negative poles of the output terminal (the sum of the actual power used by the resistor is greater than or equal to 10% of the rated power and the rated power of the selected resistor must be greater than 5 times of the actual power used, otherwise the temperature of the resistor will be higher)
