Product Overview: Texas Instruments TPS63061DSCR

The TPS63061DSCR from Texas Instruments is a high-efficiency, single inductor buck-boost converter that is designed to provide a stable and flexible power supply solution. This compact, integrated circuit is capable of operating from a wide input voltage range of 2.5V to 12V, making it suitable for applications powered by lithium-ion batteries, USB ports, and multi-cell batteries.

With its automatic transition between step-down (buck) and step-up (boost) modes, the TPS63061DSCR ensures seamless operation across varying input voltages, delivering a stable output voltage even when the input voltage is above, below, or equal to the output voltage. This feature is particularly valuable for portable devices that require a constant voltage supply despite fluctuating battery levels.

The device can provide output currents up to 2A in buck mode and 800mA in boost mode, while maintaining a high efficiency over the entire load current range. This efficiency is achieved through its integrated low RDS(on) MOSFET switches, which also help in reducing the overall thermal footprint of the system.

Key Features:

• Wide input voltage range from 2.5V to 12V.
• Adjustable output voltage range from 2.5V to 12V.
• Automatic transition between buck and boost modes for consistent output voltage.
• Efficiency up to 96%, reducing energy loss.
• 2A maximum output current in buck mode, 800mA in boost mode.
• Low RDS(on) MOSFET switches for improved thermal performance.
• 2.4MHz fixed switching frequency, enabling the use of small inductors.
• Over-temperature and over-current protection for enhanced safety.
• Power-save mode for improved efficiency at light loads.

The TPS63061DSCR comes in a small 10-pin VSON package, which is ideal for space-constrained applications. Its compact size, combined with the minimal number of external components required, makes it an excellent choice for portable electronics such as smartphones, tablets, and power banks.

Overall, the TPS63061DSCR is a versatile power management solution that offers designers the flexibility and efficiency required for modern electronic devices. Its ability to provide a stable power supply under varying conditions makes it a reliable choice for a wide range of applications.
