Parallel Operation
Parallel operation of NCP3121 circuit(s) has several
advantages. One of the most important aspects is the
capability to deliver a double output current. The major
advantage is a reduced output voltage ripple in case of
out ? of ? phase synchronization. The standard configuration
is shown in Figure 71.
OLM in Parallel Operation
When OLM is detected (e.g., a jump from 4 A on the
output to 6 A), the output voltage decreases. When OLM
wears off, the output current must be decreased below 3.5 A.
Then, the output voltage is released and current can be
increased again ? up to 4 A.
