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 for each output and can start up monotonically into a prebiased output. The IC can be configured in either PWM or DCM modes of operation, depending on whether constant-frequency operation or light-load efficiency is desired.
The IC operates over the -40°C to +125°C temperature range and is available in a lead(Pb)-free, 7mm × 7mm, 32-pin TQFP, package.
