Descripción
- MAXREFDES1039, Reference Design for 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 degree 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 latch-off limits MOSFET power dissipation under short-circuit conditions. The IC provides independent adjustable soft-starts/stops for each output and can start up monotonically into a pre-biased 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
