# TPS65124 Product Series Introduction
## Overview
The TPS65124 product series is a remarkable offering in the realm of power management integrated circuits (PMICs) developed by Texas Instruments. These highly integrated PMICs are designed to meet the complex power requirements of a wide range of applications, providing a comprehensive and efficient power solution.
## Key Features
### High - Integration
- **Multiple Voltage Rails**: The TPS65124 series integrates multiple voltage regulators on a single chip. This includes step - down (buck) converters and low - dropout (LDO) regulators. For example, it can provide multiple regulated output voltages simultaneously, which is crucial for powering different components of a system such as microcontrollers, memory chips, and sensors. This high level of integration reduces the need for multiple discrete power components, saving board space and simplifying the overall design.
- **Integrated Power Sequencing**: It comes with built - in power sequencing capabilities. This ensures that the different voltage rails are powered up and down in the correct order, which is essential for the proper operation and reliability of the system. Incorrect power sequencing can lead to system malfunctions, data corruption, or even damage to components.
### High Efficiency
- **Buck Converters**: The buck converters in the TPS65124 series are designed to operate with high efficiency. They use advanced switching techniques and low - resistance power MOSFETs to minimize power losses during the conversion process. This results in less power dissipation as heat, which is beneficial for both the overall power consumption of the system and the thermal management. For applications where battery life is a critical factor, such as portable devices, the high - efficiency buck converters can significantly extend the battery runtime.
- **LDO Regulators**: The LDO regulators also offer good efficiency, especially in low - dropout conditions. They are capable of providing a stable output voltage even when the input - to - output voltage difference is small, which is important for powering sensitive components that require a clean and stable power supply.
### Wide Input Voltage Range
The TPS65124 series can accept a wide range of input voltages. This flexibility allows it to be used in various power source scenarios, such as battery - powered applications where the battery voltage may vary over time, or in systems powered by different power adapters with different output voltages. For example, it can handle input voltages from a few volts up to a relatively high voltage level, making it suitable for a diverse set of applications.
### Adjustable Output Voltages
- **Programmable Buck Outputs**: The output voltages of the buck converters in the TPS65124 series can be easily adjusted. This is typically done through external resistors or by using digital control interfaces. The ability to adjust the output voltage allows designers to tailor the power supply to the specific requirements of the load components. For instance, different microcontrollers may require different core voltages, and the adjustable output voltage feature enables the PMIC to meet these diverse needs.
- **LDO Output Adjustability**: Similarly, the LDO regulators also offer adjustable output voltages. This provides additional flexibility in powering different types of components with varying voltage requirements.
### Protection Features
- **Over - Voltage Protection (OVP)**: The TPS65124 series is equipped with over - voltage protection circuits. In case the input or output voltage exceeds a predefined safe level, the OVP circuit will quickly take action to protect the connected components from damage. This can prevent catastrophic failures in the system due to voltage spikes or incorrect power supply settings.
- **Under - Voltage Lockout (UVLO)**: UVLO ensures that the PMIC does not operate when the input voltage is below a certain threshold. This protects the system from operating in an unstable or unreliable state when the power supply is
