MAX17548EVKIT# by Analog Devices

42V, Dual-Output, Synchronous Step-Down Controller


The MAX17548 is a dual-output, synchronous step-down controller that drives nMOSFETs. The device features a peak-current-mode, constant frequency architecture, allowing it to operate up to 2.2MHz. The device can be configured as two single-phase, independent 10A power supplies or as a dualphase, single-output 20A power supply. The device also provides the ability to run two controllers 180° out-of-phase to reduce the power loss and noise due to the input-capacitor ESR. The IC supports current sensing using either an external current-sense resistor for accuracy or an inductor DCR for improved system efficiency. Current foldback limits MOSFET power dissipation under short-circuit conditions. The IC provides independent adjustable soft-start 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, 32-pin TQFN, 5mm x 5mm package with an exposed pad.
