The TPS40056PWPR is an integrated circuit (IC) component developed by Texas Instruments. It is a synchronous buck controller that serves as an essential component in power management applications. This device offers several key features and functionalities that make it a popular choice among designers in various industries.
First and foremost, the TPS40056PWPR is highly efficient, thanks to its advanced features like voltage positioning and voltage feed-forward technologies. It can operate over a wide input voltage range of 4.5V to 18V, enabling its use in a broad range of applications. This wide input voltage range allows the device to be used with both single-cell and multi-cell battery packs.
The TPS40056PWPR supports a wide output voltage range, which can be programmed from 0.8V to 5.5V using external resistors. This flexibility makes it suitable for various applications, including processors, memory modules, and other low voltage systems.
One of the notable features of this component is its ability to operate in different modes. It has options for pulse-frequency modulation (PFM) and pulse-width modulation (PWM) modes. The device can automatically switch between these modes for better efficiency. In light load conditions, it operates in PFM mode, enabling it to achieve high efficiency with a reduced power consumption. In heavier load conditions, it switches to PWM mode for better regulation
