MAX17673/MAX17673A power management integrated circuits (PMIC) integrate a 60V high voltage (HV), high efficiency synchronous DC-DC buck regulator and two 5.5V high efficiency synchronous DC-DC buck regulators. All three regulators offer integrated power MOSFETs.The HV regulator operates from a 4.5V to 60V input voltage range and the LV regulators operate from a 2.7V to 5.5V input voltage range. The HV regulator supports load currents up to 1.5A, and can regulate output voltages from 0.9V to 5.5V. The LV regulators support load currents up to 1A, and can regulate output voltages from 0.75V to 4.8V.MAX17673/MAX17673A offer independent peak current mode control, hiccup mode overcurrent protection, ENABLE input and Power OK signal in the three regulators. The switching frequency is adjustable between 1MHz and 4MHz in the LV regulators, and the HV regulator can be programmed to run at a fractional switching frequency of the LV regulators. The HV regulator offers an adjustable soft-start function, while the LV regulators present internally fixed soft-start. Users can choose to operate the devices in either pulse frequency modulation (PFM) or forced pulse width modulation (PWM) scheme.The devices are available in a 28-pin, 5mm x 5mm TQFN package and operates over a -40°C to +125°C temperature range.ApplicationsBase Station Power SuppliesDistributed Supply RegulationFPGA/CPLD Power SuppliesHigh Voltage Single Board SystemsIndustrial Control Power Supplies
