The TPS630702RNMR is a high-efficiency, low quiescent current buck-boost converter from Texas Instruments, a leader in semiconductor solutions. This versatile power management integrated circuit (IC) is designed to manage power supply requirements in systems that require a battery to provide a stable voltage regardless of whether the battery voltage is above or below the desired output voltage.

With a wide input voltage range of 2.5V to 12V, the TPS630702RNMR can support applications powered by various battery chemistries, including single-cell Li-Ion or Li-polymer, 3 to 4-cell alkaline, NiCd, NiMH, and inputs derived from automotive sources. The device ensures a stable output voltage in the range of 2.5V to 12V, which can be set by the user through external resistors.

The TPS630702RNMR operates with a switch current limit of up to 2A in buck mode and 2.5A in boost mode, making it suitable for a wide array of portable and mobile devices, as well as for powering sensors, microcontrollers, and wireless modules in industrial and automotive applications.

Efficiency is a key feature of the TPS630702RNMR, with values typically above 90%, thanks to its 1.8MHz fixed switching frequency that reduces the size of external components. Moreover, the device incorporates a Power Save Mode that maintains high efficiency over a wide load current range. This mode is particularly beneficial for battery-powered applications, as it extends battery life by reducing the quiescent current to as low as 50µA during light load or standby operation.

The TPS630702RNMR is packaged in a compact 16-pin VQFN (RNMR) package, making it an ideal solution for space-constrained applications. Furthermore, the device features over-temperature and over-current protection, enhancing system reliability and safety. Its flexible design, high efficiency, and robust protection features make the TPS630702RNMR a preferred choice for designers looking to optimize power management in their next-generation electronic products.
