TL497ACD is a DC-to-DC adjustable switching regulator from Texas Instruments and is classified as a PMIC (Power Management Integrated Circuit). The regulator is designed to convert DC input voltage such as primary battery, input adapter, or wall switch mode power supply, into a regulated DC output voltage. Depending on the design, the voltage may range from 2V to 30V and a peak current output of up to 5A.

The TL497ACD operates by controlling the output voltage through the regulation of an inner-ring voltage, which is then compared to the input voltage. This regulation occurs through an on/off switching action of a series of switching transistors. The TL497ACD features a constant-frequency, pulse width modulation (PWM) control with a 0.2V feedback voltage. By monitoring the output voltage, the voltage regulator maintains the output voltage within a tightly-regulated range.

The TL497ACD is typically used in applications such as motor controllers, digital control systems, and medical devices. It is capable of highly efficient voltage conversion which makes it suitable for battery-operated applications. Furthermore, the device is designed to operate from a wide input supply range and can easily be adjusted to provide a wide range of output levels from 0.25V to 28V. The device also offers a current limiter to protect the output voltage from overloading.

Overall, the TL497ACD is an attractive option for projects requiring high efficiency and wide adjustable voltage control. It provides a range of features, such as short-circuit protection and thermal protection, making it a great choice for engineers and hobbyists looking for a reliable and accurate voltage regulator. Furthermore, its small size allows it to be used in a wide variety of applications.
