TPS54226PWP is a DC-DC buck converter with low noise, high PSRR, and a wide range of application fields, which makes it ideal for battery powered system. It operates from an input voltage range of 3V to 36V and delivers a regulated output voltage down to 0.6V with a 1.5A output current. It has a wide output voltage range, adjustable soft start, and has fixed switching frequency of 1MHz and allows user programmable current limit.

Working Principle

The TPS54226PWP works on the principle of switch-mode voltage regulation. It uses power transistors to switch the input voltage to achieve the desired voltage output. During the on-time of the switching transistor, a relatively large current flows from the input power source through the power transistor. During the off-time, the current stored in the inductor flows to the output. Control of the on-time and off-time of the power transistor determines the output voltage.

Application Fields

The TPS54226PWP is a perfect choice for high current, low noise DC-DC converter applications where battery power is the source. Applications such as portable medical devices, instrumentation and test equipment, industrial and consumer power systems, automotive power tools, and renewable energy sources, mobile phones and digital cameras can make use of the TPS54226PWP.

The TPS54226PWP is also ideal to be used in parallel output applications since it offers adjustable current limiting, over-temperature protection, and adjustable soft start. Its low drop out voltage and dynamic lossless DCR current limiting make it an excellent choice for high density, low power applications. Additionally, the wide temperature operating range, low output noise, high PSRR, and low quiescent current offered by this DC-DC converter make it the right choice for noise sensitive applications.

Overall, the TPS54226PWP is a highly efficient, low noise, and wide range DC-DC converter which makes it an ideal solution for power management in a vast range of applications. With its adjustable current limit, low drop-out voltage, and wide operating temperature range, it can be used in a variety of applications with ease.
