Working Principle of MAX16120KA+

The MAX16120KA+ integrates four high-efficiency, low-noise DC/DC buck converters, programmable linear regulators, a ±3ppm low-drift voltage reference, a supervisor, and a real-time clock featuring ±1ppm accuracy from 1Hz to 100MHz. The converters include two step-down converters, one step-up converter, and one boost converter. The step-down converters are designed to provide regulated output voltages of 0.8V to 6V with a maximum switching frequency of 1.2MHz. The step-up converter is designed to provide regulated output voltages from 0.8V to 6.5V with a maximum switching frequency of 1.5MHz. The boost converter is designed to provide regulated output voltages from 4V to 15V with a maximum switching frequency of 1.5MHz.The linear regulators provide accurate regulation of output voltages from 0.8V to 5V, with a maximum current capability of 10mA and a minimum dropout voltage of 120mV. The output voltage of the linear regulators can be programmed using resistor dividers connected to the ADJ pin.The voltage reference provides an output voltage of 1.2V with a maximum drift of ±3ppm and a maximum output current of 2mA. The voltage reference is ideal for providing precise regulation and accurate timing in battery-powered and low-noise systems.The supervisor is a low-voltage, low-current circuit that protects against overvoltage, undervoltage, and current overcurrent conditions. It includes adjustable threshold voltages for voltage and current detection, as well as a reset time-out period to reset the system after an overcurrent or overvoltage condition has been detected.The MAX16120KA+ also features two real-time clock circuits that provide precise timing with ±1ppm accuracy from 1Hz to 100MHz. The real-time clock circuits can be used to synchronize the various converters and regulators, ensuring a stable output and precise timing.
