The TPS54294R is a high-performance, low-profile, 3.3V dual buck DC/DC converter with a wide range of applications. It is well suited for fast-response applications in computing, communications, and industrial applications.

The TPS54294R is a high-efficiency, ultra-compact DC/DC converter with a high switching frequency of up to 2 MHz. It offers high output current levels of up to 5 A (peak) and operates in a wide input voltage range of 4.5 V to 13.2 V. Its adjustable output voltage range is 0.6 V to 3.3 V, and it can be configured in a variety of ways including output current limit and remote sense.

In applications that require moderate output current, the device can be used as a simple 2-channel buck regulator for powering a 2-phase or 3-phase VRM. With its adaptive circuitry and fast transient response, the device is also ideal for powering advanced graphical cards, such as the ATI HD 6000 series.

The TPS54294R is a synchronous, constant-current and constant-voltage (CC/CV) type buck regulator with internal output voltage setting. A programmable, low-impedance PWM controller is used to provide a constant switching frequency while also ensuring a low-noise, constant-voltage output. The dynamic response of the power stage is improved by a technique called active asynchronous rectification, which results in a low-ripple and cleaner output. In addition, the device also has built-in soft-start, current-limit, under-voltage lockout and thermal shutdown protection functions.

The device is also capable of operating in a tracking mode, where the output voltage follows the input voltage, providing a maximum output current. This operating mode is particularly useful in applications requiring tight regulation of output current, such as those found in point-of-load (POL) applications.

The TPS54294R is designed to be used in a variety of applications, including power conditioning for distributed power systems, providing power to multiple ASICs or FPGAs, serving as a low-power bus regulator for distributed systems and powering relatively low-power FPGAs.

Overall, the TPS54294R is a high-performance, low-profile, dual buck DC/DC converter with a wide range of applications. Its high switching frequency, low-noise output and adaptive circuitry make it a great choice for powering a variety of digital signal processing and graphics applications.
