TPS61014DGSR is a low cost DC-DC switching regulator integrated circuit (IC) designed for usage in portable applications needing low power consumption. This regulator has a 3µA quiescent current, an adjustable 9.3V to 13.4V output voltage, and a large output current of 1.5A. The IC is particularly suitable for audio, battery powered applications, and applications requiring long battery life such as wearable health devices.

In brief, the working principle of TPS61014DGSR is based on a step-down DC-DC switching regulator. This regulator operates in two stages: first, it converts the input power to a higher input voltage with the help of an electric lock driver, a switching regulator and a pulse-width modulated (PWM) control circuit. The PWM controller then controls the output voltage for the required regulation level.

TPS61014DGSR has a wide range of applications. It is often used for mobile/portable audio, medical, and measurement systems. It is also well suited for direct powering of low power components, such as USB peripherals, low-power LED lighting, and different battery powered applications.

This IC is designed for use in small form factor applications. Its small size and excellent transient response makes it suitable for size-constrained products. Furthermore, its low quiescent current makes it well suited for applications with constantly varying loads or those requiring high efficiency.

TPS61014DGSR features high power density with a Maximum Power Dissipation (MPD) range of 1.3W to 2.2W. Its output voltage is adjustable and current-limited. The adjustable output voltage range is 9.3V to 13.4V with two independent regulators that feature an adjustable current-limit of 0.8A to 1.5A. This IC is also protected by undervoltage, overvoltage, thermal, and current-limit protections.

Overall, the TPS61014DGSR integrated circuit is designed for low-power applications requiring low quiescent current, adjustable output voltage, small size and high output current. This regulator is particularly suitable for audio, medical and battery powered applications.
