Dual-Phase, Parallelable, Average-Current-Mode
Controllers
Detailed Description
The MAX5038A/MAX5041A (Figures 1 and 2) average-
current-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 MAX5038A/MAX5041A regulators to increase
the output current capacity. For maximum ripple rejec-
tion at the input, set the phase shift between phases to
90° for two paralleled converters, or 60° for three paral-
leled converters. The paralleling capability of the
MAX5038A/MAX5041A improves design flexibility in
applications requiring upgrades (higher load).
