MAX17558 Datasheet (Maxim) - Step-Down Controller

MAX17558, Step-Down Controller

The MAX17558 is a dual-output, synchronous step-down controller that drives nMOSFETs.

The device uses a constant-frequency, peak-current-mode architecture.

The two outputs can be configured as independent voltage rails.

Input capacitor size can be minimized by running the two outputs 180º out-of-pha
