TL5001AQD is an efficient, low-cost pulse-width-modulated switching controller designed for use in low-voltage DC-DC conversion applications. It is a part of the TL5001 series of DC/DC switching controllers, which offer superior performance, cost savings, and flexibility compared to traditional linear voltage regulators, offering high efficiency and fast transient response in a small package. It features an adjustable over-temperature protection circuit and advanced power switching protection circuit, and provides reliable, precision control of output voltage. Moreover, it has full thermal protection, current limiting, and inrush current limit makes the TL5001AQD ideal solution for portable applications with high reliability.

The TL5001AQD integrates a constant frequency voltage-mode buck converter with a 0.5A integrated buck driver based on a linear low-voltage regulator architecture. The buck driver offers an adjustable over-temperature protection circuit and advanced power switching protection circuit. The voltage-mode control architecture provides fast transient response, achieving high efficiency even at light loads. This allows for flexible output, and from 3V to 16V output range.

The device is capable of operating with supply voltages from 5.3V to 28V, allowing for operation in multiple input voltage ranges. The TL5001AQD\'s comprehensive protection features provide over-voltage, under-voltage, over-temperature, over-current and output short-circuit protections, making it a safe and reliable DC-DC switching controller solution. The wide operating temperature range ensures reliable performance even in extreme temperatures.

TL5001AQD\'s typical application is a battery-operated portable device, such as a laptop, camera and portable electronic device. It can be used to regulate the voltage of the battery, protect the device from over-voltage and under-voltage, and provide a precise output voltage for proper functioning of the device. For such application, the TL5001AQD is ideal because of its precise output voltage control, low-cost and wide operating temperature range.

The TL5001AQD is ideal for use in a range of applications, from industrial and commercial power supplies to mobile power applications. It can provide excellent performance in any environment, including 24/7 duty cycles, high humidity and extreme temperatures. In addition, its fast transient response makes it well suited for applications where light loads require high-efficiency operation and fast transient response. The TL5001AQD is available in a small 3mm×3mm 8-pin package and requires very few external components to complete the DC-DC switching controller solution.
