The TL1963ADCQT is a synchronous step-down regulator designed for battery-powered applications. It utilizes a synchronous rectified Internal Power MOSFET topology to optimize efficiency and reduce size and cost. The device operates with input voltages ranging from 4.5V to 18V and provides an output current of up to 2A. The device includes an adjustable output voltage range of 0.6V to 5.5V.

The TL1963ADCQT linear voltage regulator is a highly-efficient, step-down synchronous DC-DC converter. It consists of an internal power MOSFET, a voltage reference, a high-speed control circuit, and a current-sensing comparator. The voltage reference is used to set the output voltage and the control circuit generates signals to control the on-time and off-time of the power MOSFET switch. The current-sensing comparator monitors the output current and limits it using a foldback current limit.

The TL1963ADCQT linear voltage regulator adopts a continuous conductionmode (CCM) of regulation for operation. In CCM, the power MOSFET switch is continually energized and toggled, the switch on-time is gradually increased until the output voltage reaches the required value. The primary benefit of this mode is its high efficiency, allowing the regulator to operate at high speed and low ripple. The device also features excellent transient response, current limit protection, over-temperature protection, and under-voltage lockout.

TL1963ADCQT linear voltage regulator can find application in a variety of end-use applications, including digital cameras, notebook computers, and other portable electronics. The device is suitable for powering digital circuits, as it is able to provide a steady output voltage with minimal ripple and noise. The device also has very low quiescent current values, allowing it to be used in battery-powered applications, where it can work with supplies ranging from 4.5V to 18V.

TL1963ADCQT step-down linear voltage regulator features a very low profile in its 5-leaded package and simple setup options. With minimum current consumption, requiring no external components other than the input and output capacitors, the device is easy to use, making it suitable for a wide range of applications. It provides power designers a compact and reliable solution that can be quickly implemented with few external components.
