Figure 13. Current sense methods.

In fig. 14 is showed a single section of a system in which several DC to DC modules can be paralleled,
typical solution whenever the load requires high current at low voltage; the converter is designed for a step
down configuration using a synchronous rectification controller (for example L6910 [1] or L6911 [2] ST de-
vice).
The L6615 reads the drop across the Rds(ON) of the OR-ing FET and the LM293 drives its gate, pulling
it down whenever a fault condition (e.g. short on the low side) appears.
A charge pump could be necessary to be sure that the ORing FET V
GS
is higher than V
GS(TH)
(depending
on the input and output voltage).
