MAX17558 - 60V, Dual-Output, SynchronousStep-Down Controller - DC-DC开关调节器 - Wide Input Voltage Dual-Output Controller Enables Design Flexibility for Industrial Applications - 美信半导体
The MAX17558 is a dual-output, synchronous step-downcontroller that drives nMOSFETs. The device uses aconstant-frequency, peak-current-mode architecture.
The two outputs can be configured as independentvoltage rails. Input capacitor size can be minimized byrunning the two outputs 180° out-of-phase.
The IC supports current sensing using either an externalcurrent-sense resistor for accuracy or an inductor DCRfor improved system efficiency. Current foldback limitsMOSFET power dissipation under short-circuit conditions.
The IC provides independent adjustable soft-start foreach output and can start up monotonically into aprebiased output. The IC can be configured in eitherPWM or DCM modes of operation, depending on whetherconstant-frequency operation or light-load efficiency isdesired.
The IC operates over the -40°C to +125°C temperaturerange and is available in a lead(Pb)-free, 32-pin TQFN,5mm x 5mm package with an exposed pad.
