* Test ripple and noise by “parallel cable” method.
With the load lower than 20%, the maximum ripple and noise of 3.3V/5V output
products will be 100mVp-p, 9V/12V/15V output products will be 2%Vo.

Wide Input Non-Isolated & Regulated, Single Positive/Negative Output
Typical application circuit
Note:
1. C1 and C2 (C3 and C4) are required and should be connected close to the pin terminal of the module.
2. The capacitance of C1 and C2 (C3 and C4) refer to Sheet 1.
3. To reduce the output ripple furtherly, C2 and C4 can be increased properly if required, tantalum
capacitor and aluminum electrolytic capacitor of low ESR may also suffice.
4. When the products used as the circuit like figure 3, an inductor named as LDM up to 10μH is
recommended in the circuit to reduce the mutual interference.
5. Cannot be used in parallel to enlarge the power for output and hot swap.

Note:
Part ① in the Fig. 4 is for EMS test, part ② is for EMI filtering; parts ① and ② can be added
based on actual requirement.
