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.
