S-8338AAIB-T8T1G is an DC/DC switching controller from the PMIC-Voltage Regulators-DC DC Switching Controllers series. The product provides high efficiency, small size, low power supply voltage and high speed switching regulation, and optimizes system efficiency with synchronous rectification.

The application field of the device is multifaceted. First, It is widely used in the mobile equipment industry. Such as tablet, smart phones, power bank and wearable devices that require ultra-low quiescent current, ultra-fast standby startup, high-efficiency step-down conversion, and stable power output with low internal ripple. Second, it is also applicable in other medical and industrial equipment, such as monitors, server power supply, base stations, and automotive systems.

The relatively low startup voltage and low quiescent current of the S-8338AAIB-T8T1G makes it ideal for mobile equipment and battery operated application. This high speed switching controller provides an external reference voltage to ensure stability during heavy load steps, and the enable signal output by the S-8338AAIB-T8T1G can be used to reset the device whenever desired. The device provides synchronous rectification to optimize system efficiency and allows adjustable input voltage between 0V to 15V with increased ripple rejection ratio.

In terms of working principle, the S-8338AAIB-T8T1G operates according to the current-mode control method. It includes an linear Regulator current source to generate a proportional current as reference for the internal error amplifier. This error amplifier compares the voltage applied to CS pin to an external feedback voltage then adjusts its output voltage accordingly. Apart from step-down operation, the device also offers constant current operation. It is achieved by monitoring an external sense resistor current, and convert it into the output voltage.

To guarantee the proper operation of the device and the connected inductor and MOSFET, the S-8338AAIB-T8T1G also provides two protection functions, current limit control and soft start. The current limit control prevents the generated current in the circuit form getting out of operating range to protect the device and the system, while the soft start eliminates the large inrush current at startup.

All in all, the S-8338AAIB-T8T1G DC/DC switching controller is an applicable and multifunctional high efficiency switch regulator. It has low power supply voltage, low quiescent current and high speed, making it perfect for battery powered application. It also provides current-mode control, current limit control and soft start for optimal performance, making it an ideal choice for all kinds of mobile and industrial applications.
