Product Overview: TPS65058RGER by Texas Instruments

The TPS65058RGER is a versatile and efficient integrated power management IC designed by Texas Instruments to meet the rigorous power requirements of modern portable and battery-powered electronics. This multi-channel device combines two step-down converters with four low-dropout regulators (LDOs), making it an ideal choice for space-constrained applications where multiple power rails are required.

Key Features

• Dual Step-Down Converters: The device includes two highly efficient synchronous step-down converters with a 2.25MHz switching frequency, which allows for the use of small inductors and capacitors, thus reducing the overall solution size.
• Multiple LDO Regulators: Four LDOs provide additional regulated voltages with low noise characteristics, further enhancing the versatility of the power management solution.
• Adjustable Output Voltage: The output voltage of the step-down converters and LDOs can be adjusted via external resistors, providing design flexibility to meet various application requirements.
• Power Sequencing: The TPS65058RGER offers programmable power-up and power-down sequencing for each regulator, which is crucial for sensitive electronics that require specific power-on sequences.
• Thermal and Overcurrent Protection: Built-in thermal shutdown and overcurrent protection safeguard the device and the end application from potential damage caused by excessive heat or current.
• Small Package: Housed in a compact 24-pin VQFN package, the TPS65058RGER minimizes the footprint on the PCB, making it suitable for portable devices where space is at a premium.
