TPS54354PWPR

PMIC - Voltage Regulators - DC DC Switching Regulators

The TPS54354PWPR is a synchronous step-down DC-DC converter designed to power medium- to high-performance system applications that require a wide input voltage range and high efficiency. This regulator offers adjustable output voltages and the ability to deliver up to 7A of output current. It has a wide input voltage range (2.2V-20V) and can provide an output voltage of up to 1.2V.

Application Field

The TPS54354PWPR regulator is suitable for applications such as computing, communications, automotive, industrial, and media processing platforms. It can be used to provide a reliable, low noise power supply for media processing cores and logic cores, as well as for other core applications. In addition, it can be used to power PCB-level point-of-load (POL) designs and off-card power architectures.

Working Principle

The TPS54354PWPR regulator utilizes a synchronous buck topology and includes an integrated power MOSFET and a low-side MOSFET. It is designed to provide a constant 0.75V to 1.2V output voltage range, making it suitable for applications that require a Low dropout voltage. The regulator also offers programmable switching frequency and integrated soft-start. This enables the designer to optimize the power consumption of the system and helps avoid high inrush currents on start-up.

The TPS54354PWPR is designed to regulate output voltage with a minimum of external components. In addition, the device provides accurate voltage regulation over the operating temperature range while achieving a high level of efficiency. The device supports Pre-Bias and Fast Transient Response, offering a timing response of less than 1nS. By having high frequency switching up to 2.5MHz, the device offers very low output ripple and fast dynamic response.

The TPS54354PWPR regulator also includes overvoltage protection, undervoltage lockout, overcurrent protection, and thermal shutdown protection. This ensures the device is protected from potential damages caused by unexpected events.
