## **Notes:**
Negative output Fig. 2 Typical application circuit
Table 1
1. The required C1 and C2 capacitors must be connected as close as possible to the terminals of the module;
2. Refer to Table 1 for C1 and C2 capacitor values. For certain applications, increased values and/or tantalum or low ESR electrolytic capacitors may also be used instead;
3. Converter cannot be used for hot swap and with output in parallel.

Notes: For EMC tests we use Part 1 in Fig.3 for immunity and part 2 for emissions test. Selecting based on needs.
## **3. Trim Function for Output Voltage Adjustment (open if unused)**
1.Positive output application: connect trim resistor to GND/Vo respectively for adjusting up/down. 2.Negative output application: connect trim resistor to GND/Vo- respectively for adjusting up/down
