Fig. 4 Positive and Negative output parallelling application circuit
Note:
1. When the products used as negative output and the input-voltage under (Vin-min+2V),C1 and C2 must be added in the circuit, and they should be placed
as near as the products' footprints. Others apply to the application-environment .
2. The capacitance of C1,C2 sees external capacitor table, it can be increased properly if required, and tantalum or low ESR electrolytic capacitors may also
suffice.
3. When the products used as the circuit like figure 7,an inductor named as LDM up to 10μH is recommended in the circuit to reduce the mutual interference.
,
4. For the product of output voltage is below 3.3V or at 3.3V, if the input voltage of model s negative output is less than 4.85V, The output need to add a dummy
load of not less than 5mA.
5. Cannot use in parallel for output and hot swap for input.
To reduce the output ripple furtherly, it is suggested to connect a “LC” filter at the output terminal, and recommended value of L is
10μH-47μH.
