Description
The MAX8659 slave contains a PWM comparator, driver, integrated MOSFETs, and bootstrap diodes to support up to 25A of output current. The IC accepts control/clock signals from the MAX8657/MAX8658 master to regulate the output inductor current. Address bits on the MAX8659 enable the slaves to decode the clock signal appropriately to implement 2/3/4/5/6/7/8-phase operation.
The MAX8657/MAX8658 incorporate a proprietary “rapid active average” current-mode control scheme for precise load sharing between phases as well as accurate droop-setting independent of inductor tolerances. Either parasitic inductor DCR or resistive current sensing is implemented.
The MAX8657/MAX8658 are available in a 56-pin 8mm x 8mm thin QFN package. The MAX8659 is available in a 40-pin 6mm x 6mm thin QFN package.
