Detailed Description
The MAX5038/MAX5041 (Figures 1 and 2) average cur-
rent-mode PWM controllers drive two out-of-phase
buck converter channels. Average current-mode con-
trol improves current sharing between the channels
while minimizing component derating and size. Parallel
multiple MAX5038/MAX5041 regulators to increase the
output current capacity. For maximum ripple rejection
at the input, set the phase shift between phases to 90°
for two paralleled converters, or 60° for three paralleled
converters. Paralleling the MAX5038/MAX5041s
improves design flexibility in applications requiring
upgrades (higher load).

12 ______________________________________________________________________________________
Dual-phase converters with an out-of-phase locking
arrangement reduce the input and output capacitor
ripple current, effectively multiplying the switching fre-
quency by the number of phases. Each phase of the
MAX5038/MAX5041 consists of an inner average cur-
rent loop controlled by a common outer-loop voltage-
error amplifier (VEA) that corrects the output voltage
errors. The MAX5038/MAX5041 utilize a single control-
ling VEA and an average current mode to force the
phase currents to be equal.
