The Texas Instruments TPS54315PWPR is a synchronous buck and boost step down DC/DC switching regulator that enables designers to optimize their designs for small size and high efficiency at the same time. It offers an input voltage range of 3.2V and an output voltage range of 0.9V to 5.5V, providing designers with a wide range of different applications. The integrated power control and monitoring features of the TPS54315PWPR allow the designer to precisely control the output voltage, while minimizing the amount of external components required.

The TPS54315PWPR is designed to operate over a wide input voltage range of 3.2V to 16V. The output voltage is adjustable, allowing the designer to optimize their designs for the desired application. The device also features over-current protection and thermal protection, providing protection for the system in the event of an over-current, or excessive heat. The TPS54315PWPR also features a low on-resistance synchronous Power MOSFET, which helps reduce the output voltage ripple and minimize overall system power dissipation, while still providing an efficient DC/DC solution.

The TPS54315PWPR is ideal for use in a variety of electronic systems such as portable computers, cellular telephones, media players, PDAs, wearable devices and automotive applications. The device can also be used for LED backlighting, battery charging and other applications that require a buck-boost configuration. The device can be used for applications that require up to 24V input voltage, up to 7A output current and up to 20V output voltage.

The TPS54315PWPR features a programmable switching frequency from 200kHz to 2.5 MHz, allowing designers to optimize their designs for the specific application. The device supports burst-mode operation, which helps reduce the power consumption when the output load is not active. The device also includes an adjustable soft-start function, allowing the output voltage to smoothly ramp up to the programmed value without over-stressing the system.

The TPS54315PWPR works on the buck and boost switching principle. The device employs an external catch-diode to ensure that the energy stored in the inductor loop is safely discharged during the switch-off times. A low quiescent current of less than 1uA is provided. The device has a wide operating temperature range of -40°C to 125°C, making it suitable for use in extreme temperature environments.

The TPS54315PWPR is well suited for a wide range of applications such as notebook PCs and other devices that require high current and low voltage conversion. The device offers a low profile package and an easy to use design, allowing designers to utilize this efficient DC/DC solution in their designs. The device is available in an exposed pad thermally enhanced package for enhanced reliability and thermal performance.
