TPS75225QPWPRQ1

TPS75225QPWPRQ1 is a 3A synchronous step-down high-side power switch with an integrated low-dropout linear regulator. It integrates a high-side MOSFET, linear regulator, and several other charge pumps and other features into a single chip. The device is optimized for low cost and a small form factor.

Primary Applications for TPS75225QPWPRQ1 include:

• PCIe & USB 3.0 Servers
• Multimedia Systems
• Network Router & Switch
• X86 & ARM-based Systems

The TPS75225QPWPRQ1 operates with an operating input voltage range of +4.5 V to +19 V and provides a fixed +5 V output. In addition, the device includes an enable pin and output voltage adjust pin that allow the user to set the output voltage to within 0.6% accuracy. The device also has separate enable and powerdown pins so that it can be easily controlled and shut down.

The device uses a simple two-phase buck switching regulator topology to achieve a low-noise power supply design. During peak-load conditions, the high-side MOSFET operates in both buck and boost phases, allowing for a high efficiency design. During light load conditions, the MOSFET operates in low loss synchronous rectification, as opposed to linear regulation, improving efficiency and reducing power consumption.

The device also includes a number of other features to enhance system performance. These include current and temperature monitoring, an integrated synchronous rectifier, programmable over-current protection, current sensing, programmable soft start, and an inverting enable input. Additionally, an on-board power good, output voltage adjust and enable pins, and integrated temperature monitoring, allow the device to be tailored to specific applications.

The TPS75225QPWPRQ1 is an ideal solution for a variety of advanced application fields, such as servers, network routers and switches, multimedia systems, and x86 and ARM-based systems. Its low cost and small form factor make it a great choice for cost sensitive and space-constrained applications.
