Introduction

The Texas Instruments TPS62000DGSR is a low-cost, low-power, low-dropout linear regulator contained in a 12-pin TSSOP package. It integrates a voltage reference with resistive divider circuit, an external shutdown input, and an adjustable or fixed output. It is a highly integrated switch-mode voltage regulator designed to meet the highest standards in power management applications, offering a cost-effective solution to a wide range of power requirements.

Application Field

The TPS62000DGSR can be used in a variety of application fields, including embedded systems, industrial automation, automotive, mobile devices, and consumer electronics. The device can also be used in applications where low cost, low quiescent current, fast transient response, and wide input voltage range is important.

Working Principle

The TPS62000DGSR is a switched-mode voltage regulator that uses an external power MOSFET and a voltage feedback control circuit to regulate an output voltage. The device utilizes a proprietary control method to minimize the power dissipation during light load conditions. The internal PWM controller regulates the output voltage by sensing the voltage on the output and adjusting the duty cycle of the power MOSFET accordingly. The power MOSFET is turned ON for the duration of the cycle and OFF when it reaches the targeted output voltage. This increases efficiency, reduces switching losses, and eliminates large input voltage drops. A dedicated current source reduces the quiescent and output peak currents allowing for small output capacitors, which vastly reduces external components. Additionally, a built-in current over-temperature detection circuit allows the TPS62000DGSR to be used in environments where thermal protection is required.

Conclusion

The TPS62000DGSR is a low-cost, low-power, low-dropout linear regulator with broad application fields. Its integrated switch-mode voltage regulator is designed to meet the highest standards in power management applications, offering a cost-effective solution to a wide range of power requirements. It combines high efficiency and low quiescent current with fast transient response and wide input voltage range, making it ideal for a variety of applications.
