The TPS63002DRCR is a high-efficiency, low dropout (LDO) switching regulator designed to deliver up to 0.8A of output current. It is part of Texas Instruments\' Power Management Integrated Circuit (PMIC) family and specifically falls within the voltage regulator subcategory of dc-dc switching regulators. This article will explain the application fields and working principle of this PMIC.

Application Fields

The TPS63002DRCR is best suited for use in industrial, consumer, and communications applications. For example, digital supplies for consumer devices such as digital music players as well as camera and digital still cameras can all benefit from using this type of PMIC due to its high efficiency and small size. In industrial applications, uses for the PMIC can range from digital supplies in computers, cell phones, and metering systems to portable electronic devices and equipment powered by external batteries. It is also suitable for use in point-of-load converters and other high-density DC-DC power supplies found in many communications system.

Features and Benefits

The TPS63002DRCR is flexible and offers several features and benefits that make it a great choice for powering a range of consumer and industrial applications. It integrates all of the main switching elements to reduce external component count and board space requirements. Additionally, it uses a Pulse Frequency Modulation (PFM) control mode and an Internal Gate Driver (IGD) to optimize performance for minimum switch-on and switch-off times. This helps the device to achieve the highest possible efficiencies. The device is also specially designed to reduce EMI from the switching element and features a low quiescent current option for use in battery-powered applications.

Working Principle

The TPS63002DRCR operates using a self-biased high-side and low-side driver with an internal voltage reference. This helps the device to efficiently switch on and off without the need for external bias components. The device also includes an internal gate driver that helps to reduce the external component count required. The integrated pulse frequency modulation (PFM) control provides a high efficiency and low noise operation that eliminates the need for external components.

The PMIC also features a high-current low-dropout (LDO) regulator with an Internal Voltage Reference. This feature helps the device to maintain a constant output voltage even with a changing input voltage and load current. Additionally, the device also includes several enhancements such as PCB layout optimizations that help to improve efficiency, reduce component count, and reduce power dissipation.

Conclusion

The TPS63002DRCR is a high-efficiency, low dropout (LDO) switching regulator ideal for use in industrial, consumer, and communications applications. The device features an integrated pulse frequency modulation (PFM) control mode with an internal gate driver and voltage reference for optimal performance and efficiency. Additionally, it also includes several enhancements for reducing component count, improving efficiency, and reducing power dissipation.
