The TPS54283PWPR is a highly efficient, integrated circuit (IC) component designed for use in power supply applications. It is a synchronous, step-down converter that can provide a regulated output voltage from a higher input voltage. This IC is manufactured by Texas Instruments and has become popular due to its small footprint and advanced features.
One of the key features of the TPS54283PWPR is its ability to operate over a wide input voltage range, from 4.5 volts to 28 volts, making it suitable for various battery and power source applications. The output voltage can be configured within the range of 0.8 volts to 85% of the input voltage. This flexibility allows for compatibility with a wide range of system requirements.
The IC offers a fixed-frequency voltage-mode control architecture. It employs a current-mode control scheme that provides accurate and stable regulation even under varying load conditions. The TPS54283PWPR incorporates a highly efficient, integrated MOSFET power switch with low RDS(ON) to minimize power losses and optimize efficiency.
Another notable feature of this IC is its internal soft-start circuitry, which allows for controlled startup and prevents excessive inrush currents, thereby protecting the power supply system. Additionally, it includes various protection features such as overcurrent protection, overvoltage protection, and thermal shutdown, ensuring safe operation and preventing damage to the IC and other components
