The TPS2147IDGQR device is a specialised type of power management integrated circuit (PMIC) created by Texas Instruments (TI). The device offers a range of features and a number of operating modes that provide flexible solutions for a variety of applications. This article will discuss the application field and working principle of the TPS2147IDGQR.

Application Field

The TPS2147IDGQR can be used in a multitude of applications, such as in data centers, automation, communications, consumer gadgets/devices and powering of FPGA/CPLDs. It is particularly useful for applications in which the power supply needs to be rapidly enabled/disabled or in applications that require a large number of smaller, independent power rails.

The device can also be used to build power supplies with high power density and low quiescent current. This can be especially beneficial in portable devices where energy efficiency is paramount. The device also features power sequencing, overload protection, and over-temperature detection and shutdown, making it suitable for use in IoT systems, medical devices, industrial systems, and aerospace applications.

Working Principle

The TPS2147IDGQR uses a multi-mode controller to enable a wide range of operating modes. The device can be set up in one of nine different operating points, including a Burst Mode Enhancement, Low-Dropout (LDO), or a Bypass/Copy/Pump mode. Each operating point provides a different level of power delivery.

In Burst Mode Enhancement mode, the device is designed to provide high power efficiency with fast transient response. It is well-suited for powering peripherals on the board. The Low-Dropout (LDO) mode is designed to provide stable output voltage while suppressing noise and EMI. The Bypass/Copy/Pump mode is particularly useful for applications that require multiple power rails with varying voltages. It allows for quick power-up sequencing and status monitoring.

The device uses a unique digital logic implementation to enable different operating modes. The Flip-Chip architecture of the device allows it to run at low operating temperatures and ensures low power losses, resulting in high efficiency operation. The digital logic implementation also allows for tight regulation, precise control, and low standby power.

The device is also capable of adaptive voltage scaling (AVS), which helps to save power and increase performance. The AVS feature allows the device to dynamically adjust the switching and output voltages to match the needs of the system, resulting in more efficient power management.

The TPS2147IDGQR device is a versatile power management integrated circuit that provides a wide range of features and a multitude of operating modes to accommodate a variety of applications. Its Flip-Chip architecture ensures high efficiency while its digital logic implementation enables precise control and tight regulation, making it suitable for a range of applications.
