## **DERATING CURVES** 

Note:     6. With an input between 250-300VDC, the output power must be derated as per temperature derating curves. 

7. This product is suitable for applications using natural convection; for applications in closed environment please consult CUI.

## **APPLICATION CIRCUIT** 

**Figure 1** 

## **Table 1** 

|||**Table 1**|||
|---|---|---|---|---|
|Vout<br>(Vdc)|Fuse|C1<br>(μF/V)|C2<br>(μF/V)|TVS|
|12|4A / 1500Vdc,<br>required|1 μF/35V|120μF/25V|SMBJ20A|
|24|||68μF/35V|SMBJ30A|
|28|||68μF/50V|SMBJ36A|



We recommend using an electrolytic capacitor with high frequency and low ESR rating for C2 (refer to manufacture’s datasheet). Choose a capacitor voltage rating with at least 20% margin, in other words not exceeding 80%. C1 is a ceramic capacitor, used to filter high-frequency noise. TVS is a recommended suppressor diode to protect the application in case of a converter failure. 

## **EMC RECOMMENDED CIRCUIT** 

**Figure 2** 

**EMC application for higher compliance requirements** (output parameters are shown in Figure 1) 

**Table 2** 

|**Table 2**|**Table 2**|
|---|---|
|Recommended External Circuit Components||
|C7|safety capacitor 474K/>1500 Vac|
|C3, C4, C5, C6|10 µF/450 Vdc|
|R1, R2, R3, R4|1 MΩ/2 W|
|LCM1, LCM2|20 mH/1 A|
|CY1, CY2, CY3, CY4|102 M/1500 Vdc|
|FUSE|4 A/1500 Vdc, required|
|D1|4 A/3000 V|



Note:     8. Adding D1 if there is a requirement of input reverse polarity protection for C3-C6. 9. Remove CY1, CY2, CY3, CY4 if no conducted emissions requirements.
