Figure 12. Parallel configuration suitable for redundant operation

Figure 13. Parallel configuration for current sharing

Notes.

1. Up to 3 converters to share within 80% max power;

2. To calculate the resistor (R) for the current sharing use the formula: R=(Vout nom (V) x output set tolerance (%))/(Iout nom (A) x current share (%)), e.g.

MTC1528S05 will be: R=(5V x 4%)/(2.40A x 50%)=167m

Ω

3. The adjust pin can be used to tune Vout to achieve max of 1% tolerance which helps to achieve better current sharing and keeps the resistor (R) value lower.
