Introduction
The TS5204CQ33 RFG is a linear voltage regulator from Texas Instruments’ portfolio of power management integrated circuits (PMIC). It is based on a modern, low quiescent current technology, and provides cost-effective power solutions for advanced energy-efficient portable device designs. The device offers a wide variety of features and enhancements, along with full regulatory compliance and high integration. It includes features such as programmable switching and adjustable current limit, as well as full over-voltage protection and thermal shutdown. Application Field
TS5204CQ33 RFG is an ideal solution for a variety of applications, including portable consumer electronics, telecommunications, wearables, and IoT devices. Its low quiescent current and high integration make it an optimal choice for these demanding applications. Its features provide support for multiple power domains and external power sources, while allowing for advanced power management and system-level tuning.Working Principle
The TS5204CQ33 RFG operates in a constant-voltage (CV) mode. This means that the device controls the output voltage by varying the current consumed from the input power source. The device is capable of adjusting the output voltage over a wide range, from 0.3 to 3.4V, and is highly efficient, with minimal losses in the form of heat generation. The device also incorporates protection features, such as under-voltage lockout (UVLO) and short-circuit protection (SCP). Additionally, the device can be configured to provide current limit protection, as well as fast overload protection, allowing it to quickly react to high inrush currents.The TS5204CQ33 RFG’s low-dropout (LDO) design features an internal error amplifier, which allows the device to adjust the output voltage based on feedback from an external resistor divider. This allows for fine-tuning of the output voltage for optimal performance. The device also allows for output voltage selection via external resistors.The device also utilizes a low-noise, low-power buck converter, which allows for efficient conversion of the input voltage to its desired value. The buck converter has an adjustable switching frequency, allowing for optimization of power efficiency and noise performance. The current limit protection feature can be configured to protect against over-current conditions.Conclusion
The TS5204CQ33 RFG is an advanced, low quiescent current voltage regulator from Texas Instruments’ portfolio of PMICs. It is suitable for a wide range of applications, including portable consumer electronics, telecommunications, wearables, and IoT devices. Its features include full-range CV operation, adjustable voltage selection and current limit protection, as well as fast overload protection. The device’s low-dropout design, low noise buck converter, and internal error amplifier allow for efficient power management with minimal losses in the form of heat generation.
