Introduction

The S-8533A50AFT-TB-U is a step-down switching regulator with embedded memory. It is a member of the PMIC - Voltage Regulators - DC DC Switching Controllers family. It is designed to produce an output voltage of 1.8V with an accuracy of 0.2% and a tolerance as small as 0.05%. In addition, it offers a wide range of operating temperature range, from -40℃ to 105℃, and a low quiescent current of 0.3mA.

Application Field

The S-8533A50AFT-TB-U is mainly used in applications where a high level of regulation accuracy and a wide operating temperature range are required. It is ideal for use in portable applications, such as mobile phones, tablets and laptops, due to its low quiescent current. Additionally, the S-8533A50AFT-TB-U can also be used in medical and industrial equipment, where a high level of current accuracy is a must.

Working Principle

The S-8533A50AFT-TB-U features a step-down switching regulator, which works on the idea of using a switch to turn the input voltage into a lower output voltage at a higher current level. In order to achieve this, the S-8533A50AFT-TB-U uses a combination of input voltage, switching frequency, switching duty cycle and inductance. The device also uses an embedded memory to store the required variable data for optimal performance.

In operation, the input voltage is applied to the S-8533A50AFT-TB-U and the device then works on the combination of variable data mentioned above to produce the desired output voltage. The device then stores the variable data in its embedded memory to ensure the same output voltage level each time the device is powered on. The output voltage is then regulated using an internal error amplifier to compensate for any changes in the input voltage. This ensures that the output voltage remains within the accuracy specifications of the device.

Conclusion

In conclusion, the S-8533A50AFT-TB-U is a step-down switching regulator with embedded memory, designed to produce an output voltage of 1.8V with an accuracy of 0.2% and a tolerance as small as 0.05%. It is ideal for use in various types of applications, such as mobile devices, medical and industrial equipment, due to its wide operating temperature range and low quiescent current. The S-8533A50AFT-TB-U works on the principle of using a combination of input voltage, switching frequency, switching duty cycle and inductance, along with an internal error amplifier to regulate the output voltage.
