60V, Dual-Output, Synchronous Step-Down Controller
General Description
The MAX17559 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 is minimized by running the two outputs 180° out-of-phase.
The IC supports current sensing using either an external current-sense resistor for accuracy or an inductor DCR for improved system efficiency. Current foldback or latchoff limits MOSFET power dissipation under short-circuit conditions.
The IC provides independent adjustable soft-start/stop...
