A6985F3V3 is a DC-DC switching regulator from PMIC (Power Management IC), which provides a cost effective power solution for embedded systems by integrating both the power regulation and power management. It is a buck converter with a wide input voltage range from 3.3 V to 32 V and an output voltage range from 0.6 V to 28 V. It is capable of delivering up to 5 A in the integrated package and up to 3 A with the control function and common package.
A6985F3V3 is designed for high efficiency and fast transient response, and is suitable for applications requiring tight output voltage accuracy and wide input voltage range, such as microprocessors, digital signal processors, ASICs, and portable electronics. Its main features include overvoltage protection, over-current protection, thermal shutdown, and power-good indicating signal, making it suitable for portable systems and low power applications.
A6985F3V3 uses a buck converter topology, which employs a top-switched structure to reduce the size of the inductor and enable higher output currents. The regulator is capable of operating with an input voltage up to 32 V and has a ±2% output voltage accuracy and a 100 kHz switching frequency. It features cycle-by-cycle current limit, hiccup mode over-current protection, and internal soft-start.
A6985F3V3 is optimized for efficient and fast load transient response, so it can achieve very fast load step response with only a small output ripple. It features a patented control scheme to reduce the output voltage ripple and improve efficiency over traditional linear regulators.
A6985F3V3 is an ideal device for applications that require tight output noise and fast transient response. It is suitable for complex power management applications, such as industrial control systems and embedded digital systems. A6985F3V3 integrates overvoltage protection and other safety features, making it suitable for portable systems and low power applications. Additionally, its low component count, small size, and high efficiency make it a very attractive solution for a variety of applications.
