The TPS62140RGTR is an integrated circuit (IC) component manufactured by Texas Instruments. It is a highly efficient and adjustable buck converter that operates with a wide input voltage range. This IC is specifically designed to cater to the requirements of compact and battery-powered applications.
One of the key features of the TPS62140RGTR is its ability to step down voltage from an input voltage range of 3V to 17V to a regulated output voltage as low as 1.2V. With a maximum output current capability of 1.5A, it can deliver substantial power depending on the input and output voltage scenarios. The high efficiency of up to 97% minimizes power losses and maximizes battery life in portable applications.
The TPS62140RGTR incorporates a fully integrated synchronous buck converter topology, which eliminates the need for external diodes while reducing solution size. This monolithic IC includes both high-side and low-side power MOSFETs, as well as control circuitry, making it a space-saving solution. Additionally, it comes in a compact 16-pin QFN package, further enhancing its suitability for space-constrained designs.
To ensure reliable and stable operation, the IC offers an advanced control scheme that includes pulse width modulation (PWM) and frequency dithering techniques. These features enable a seamless transition between different operating modes (e.g., PWM or Power Save Mode) depending on the load, optimizing efficiency across the entire load range
