Figure 13. Paralleling Multiple Power-Supply Modules for Current Sharing
When the MAX5051 is used as the primary-side con-
troller, additional benefits are also realized with its spe-
cial paralleling pins. The MAX5051 allows simultaneous
shutdown and wake-up, as well as frequency synchro-
nization and 180 degree out-of-phase operation of
each connected primary.
The current-share loop consists of the following func-
tional blocks:
? A diode ORed force amplifier that connects with the
other modules and forces the bus to carry a voltage
proportional to the highest current among the mod-
ules.
?
?
?
?
A sense amplifier that senses this share-bus volt-
age and applies it to internal circuitry.
A fixed gain of 20, current-sense amplifier that
senses the output current through a sense resistor.
A current-adjust amplifier that functions as an error-
amplifier block in the current-share loop.
A voltage-to-current (VtoI) block that adds a small
amount of current to the reference current, increas-
ing the reference voltage and enabling the module
to share more current.
