Introduction to TPS70102PWP

The Texas Instruments TPS70102PWP is a Linear PMIC (Power Management IC) Voltage Regulator. It\'s part of the Ultimate Power and Performance (U_Power) family, the world\'s smallest and most efficient power delivery solutions for portable applications, and it offers the best combination of low-cost, low-power and high accuracy between a couple of applications.

TPS70102PWP Features

The TPS70102PWP is capable of providing up to 300mA load current at a wide range of operating voltages from 12V down to 1.2V (95% efficiency at 1.2V). It features a high-side control output which allows it to be easily integrated into a wide range of power management architectures. It also includes an enable pin that can be used to enable or disable the output, as well as a foldback output pin which can be used to limit the output voltage. Additionally, the TPS70102PWP includes over current, over temperature, and short-circuit protection circuits.

TPS70102PWP Application Field

The TPS70102PWP is ideally suited for Power over Ethernet (PoE), wireless communications, consumer electronics, industrial control and power supply applications. It can also be used for battery charging, data acquisition and medical diagnostic equipment. With its wide operating range, the TPS70102PWP is well suited for mobile applications, such as smartphones, tablets, and embedded systems.

TPS70102PWP Working Principle

The TPS70102PWP is based on an adaptive on/off control mechanism. This mechanism continuously monitors the output current, adjusts the power on/off switching time, and effectively maintains the output voltage within its specified accuracy range. The TPS70102PWP is designed with a Constant Frequency/Current Mode Pulse Width Modulation (PWM) regulator. This PWM regulator is used to control the voltage output of the regulator. By overlapping the power on/off switching time, voltage regulation is maintained to within the specified accuracy. This overlapping is done through Pulse Frequency Modulation (PFM) and a peak current mode control (PCM). When the output load is below its set current limit (I_SET), the PFM signal is generated, allowing the regulator to remain in the PFM mode. As the load current increases towards its threshold, the TPS70102PWP will then enter the PWM power saving mode. In this state, the TPS70102PWP utilizes the PCM to overlap the power on/off switching time, so as to maintain the output voltage within the set tolerance.

Conclusion

The Texas Instruments TPS70102PWP Linear PMIC Voltage Regulator is an excellent choice for applications that require a high current, low power, and high accuracy regulator. Its wide operating range and built in protection circuits make it suitable for many different types of applications. Its adaptive on/off control mechanism, constant frequency/current mode PWM, and peak current mode control enable it to maintain the output voltage within the specified accuracy regardless of load current. With its advanced features, the TPS70102PWP is ideal for power delivery solutions for portable applications.
