The RT8296AHGSP is a DC-DC buck converter with dynamic voltage scaling, which is designed for Adaptive Voltage Scaling (AVS) applications. It’s designed to reduce power consumption and improve efficiency for mobile applications. The RT8296AHGSP is capable of taking a wide input voltage range of 2.4V to 6V and output a fixed voltage of1.3V to 5V.

Application of RT8296AHGSP

The RT8296AHGSP is ideal for mobile applications due to its compact design, ultra-low supply current, low shutdown current, wide input voltage range and ultra-fast load transient response. It’s suitable for powering voltage sensitive applications such as LCD display, camera, processor, and other integrated circuits. With its programmable soft-start feature, the RT8296AHGSP can effectively balance efficiency and load transient response.

Working Principle of RT8296AHGSP

The RT8296AHGSP operates in discontinuous conduction mode (DCM) or current-mode control. The input voltage is converted to the desired output voltage via switching devices. In the ideal voltage mode, the duty cycle of the switching devices alters to reach the desired output voltage. In the adaptive voltage scaling (AVS) mode, it senses the application environment and adjusts the voltage to meet the requirement. The RT8296AHGSP also features an ultra-fast transient response, where the loop response time is shorter than a few microseconds.

Advantages of RT8296AHGSP

The RT8296AHGSP provides several advantages over other DC-DC converters. Its programmable soft start feature can provide fast, consistent voltage output with less inrush current, while its over-temperature protection and over-load protection feature provide safe and reliable operation. In addition, the RT8296AHGSP can also save power by preventing overvoltage and enabling voltage levels matching the application requirement.

Conclusion

The RT8296AHGSP is a DC-DC buck converter designed to reduce power consumption and improve efficiency for mobile applications. It has a wide input voltage range of 2.4V to 6V and output a fixed voltage of 1.3V to 5V. It features an adaptation voltage scaling function and provides programmable soft-start feature, over-temperature protection, over-load protection and power-saving features. The RT8296AHGSP is suitable for powering voltage sensitive applications such as LCD display, camera, processor, and other integrated circuits.
