The TPS54352PWPG4 is a synchronous buck DC/DC switching regulator designed to supply power to small system load, such as ASIC, FPGA, ARM or DSP. It has a number of features that make it suitable for use in applications that require high performance, low-noise power supply. It is a synchronous buck DC/DC converter capable of delivering up to 12 A of output current at an input voltage of 4.5 V to 25 V. The TPS54352PWPG4 features a low noise, tightly regulated linear mode output as well as 3 peak current limit modes for design optimization. The device also offers a wide range of output voltage settings that can be selected with external resistors. With a synchronous frequency of 1.6 MHz, the device can provide a stable output voltage with minimal component count exterior the device.

The working principle of the TPS54352PWPG4 is based on the buck converter topology. It comprises an input current loop and an output current loop, as well as two transistors (switching transistors)—M1 and M2, an inductor, and several capacitors. The input voltage from an external source is fed to the converter, and the input current is passed to the switching transistors, M1 and M2. When the transistor M2 is switched on, it allows current to flow through the inductor and the load, and voltage is built up at the output. However, when the transistor M2 is switched off, the stored energy in the inductor is released, and current is supplied to the output load. This process is repeated at the switching frequency of the device, and the output voltage can be regulated by controlling the duty cycle of the switching transistors.

The TPS54352PWPG4 is an advanced synchronous buck DC/DC converter ideally suited for portable and battery-powered applications. It has the capability to support a wide range of input and output voltages and can provide up to 12 A of output current. It is also highly efficient, and its frequency can be programmed to optimize efficiency and reduce noise. The device can be used in applications that require high performance, low-noise power supply such as ASIC, FPGA, ARM, or DSP.
