TPS650003RTET Application Field and Working Principle

TPS650003RTET is an ultra-low noise, high performance DC/DC power management integrated circuit (PMIC) from the Texas Instruments’ TPS65000 series of digital power controllers. It is used in both consumer and medical designs to enable products to achieve higher levels of efficiency. This PMIC belongs to the “Specialized” category of Power Management, and it is designed for low power smart phone and other mobile applications offering multiple output voltage and dynamic power management functionality.

This part offers full-feature dynamic power management with four step-down (buck) converters, two step-up (boost) converters, and two low dropout (LDO) voltage regulators, combining both fixed and adjustable output voltage rail support. The fixed output voltage is the most common, though the adjustable output voltage rail is another option when the application requires a customized output voltage between 0.9V and 1.35V. The LDOs are used for linear regulation and provide stable power to the external loads.

The buck converters of the TPS650003 offer high efficiency, wide load range and fast transient responses. They also allow for different configurations such as fixed frequency, PWM controlled, burst mode, and pulse skipping. In addition, the TPS650003 has the capability to address in-rush current and the power demands of the low power application. The step-up converters provide a higher @ voltage output for applications requiring more power, such as battery charging.

The TPS650003 is a versatile device that can be used in many designs, including smartphones, tablets, IoT, wearable and consumer electronics applications requiring tight regulation and excellent energy efficiency. Its advanced features and low noise operation make it ideal for mobile and IoT applications requiring battery life extension, such as used in hearing aids and other healthcare applications.

In order to ensure optimal performance, the PMIC is equipped with a number of built-in protection features such as over temperature protection, reverse current protection, and programmable limits to protect the system against sudden or accidental power surges or current consumption. These features provide system designers with the assurance and additional level of safety and reliability.

The TPS650003 also supports a variety of dynamic power management (DPM) functions. These include Power Gating and Adjustable Power output options that allow for reduced power consumption, improved design flexibility, and longer battery life. This dynamic power management enables the TPS650003 to offer high system efficiency and accuracy when managing the power distribution across its multiple outputs.

Overall, the TPS650003 is a highly efficient and reliable PMIC, ideal for a variety of low power and high current applications requiring high performance, wide load ranges, low noise, and dynamic power management features.
