S-873023CUP-AFCT2G Application Field and Working Principle

PMIC, or Power Management ICs are integrated circuits that are designed to monitor, control and regulate electrical systems in electronic devices. Voltage regulators are an important part of this power management system and are generally used to supply a steady voltage to electronic circuits. Special purpose voltage regulators, such as the Texas Instruments S-873023CUP-AFCT2G, help to extend the capabilities and provide additional features when compared to traditional regulators.

S-873023CUP-AFCT2G Application Field

The S-873023CUP-AFCT2G is a compact, high efficiency dual phase synchronous buck voltage regulator from Texas Instruments. It is designed to provide a regulated 3.3V output from input voltages between 3.7V and 17V. The high efficiency of this regulator makes it ideal for applications such as industrial motor control and communications. It can also be used in automotive applications such as in-vehicle systems and body electronics.

In addition, this voltage regulator is ideal for many space and power constrained applications, such as medical devices, implantable medical devices, cellular base stations and more. The integrated switches of this regulator reduce component count and board space compared to more traditional regulators.

S-873023CUP-AFCT2G Working Principle

The S-873023CUP-AFCT2G is a dual phase synchronous buck voltage regulator. It uses two power stages to provide a regulated voltage at the output. The two power stages are arranged in a push-pull topology and are connected in parallel with a low impedance ground path to reduce noise. This allows the voltage regulator to achieve a high efficiency while keeping the ripple voltage at a minimum.

The power stages are connected to an independent loop control module that uses current mode control to regulate the output voltage. This control module monitors the output voltage and adjusts the two power stages to maintain a constant output. The control module also features a programmable slew rate and soft start to reduce inrush current, which makes it ideal for applications that require output voltage control in low voltage environments.

To ensure a high efficiency, these voltage regulators also feature integrated MOSFETs and P-channel power transistors. The integrated MOSFETs provide better thermal regulation and low on-resistance for improved power and efficiency. The P-channel MOSFETs also provide better protection from reverse connection of the input pins and lower standby power consumption for improved power efficiency.

Overall, the S-873023CUP-AFCT2G is an ideal choice for applications that require power and space savings in low voltage environments. It provides a high efficiency, low ripple voltage and accurate voltage regulation in a small package. This makes it a suitable option for applications that require power and space efficiency, such as industrial motor control, vehicle systems and medical devices.
