Dual-Phase, Parallelable, Average Current-Mode
Controllers
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).
