The MAX16956AUBA+T is a dual step-down regulator from Maxim Integrated that is designed to be a low-noise, high-efficiency power management solution. It is comprised of two independent, single-phase pulse width modulation (PWM) step-down regulators that provide good transient response and offer excellent system performance. These regulators convert a positive voltage input to a lower positive voltage, or a negative voltage input to a higher negative voltage, ideal for powering applications such as system-on-chip (SoC) memory device and RF amplifiers.

The MAX16956AUBA+T has a maximum input voltage of 36VP, a maximum switching frequency of 1.5MHz, and an operating junction temperature range of –40°C to +125°C. This regulator operates from a 2.7 V to 5.5 V power rail and is protected from short circuits, thermal shutdown, and undervoltage lockout. The output voltage range on the MAX16956AUBA+T can be set to 0.6 V to 5.5 V, ensuring compatibility with a wide range of devices. An internal compensation block on the MAX16956AUBA+T generates an adjustable frequency triangle wave. The device utilizes pulse-width modulation (PWM) to convert the input voltage to a stepped-down voltage, making it ideal for power-sensitive applications.

The MAX16956AUBA+T has a wide array of features specifically designed for automotive systems. It is qualified to AEC-Q100 grade 2 and has features such as the TDFN-8L package for better thermal performance, over-voltage protection and a wide ambient temperature range. Additionally, the device features integrated soft-start for improved start-up performance, as well as frequency synchronization for noise reduction.
