The TPS54350PWPR from Texas Instruments is a 3A synchronous step-down (buck) converter designed for efficient power management. It operates with an input voltage range of 4.5V to 20V and provides an adjustable output voltage down to 0.9V with 1% accuracy. The device features integrated FETs, synchronous rectification for high efficiency, and a low-side gate driver.
Key electrical specifications include a maximum output current of 3A, a switching frequency that can be fixed at 250kHz or 500kHz, or adjusted from 250kHz to 700kHz. It has a typical quiescent current of 0.005A and a maximum duty cycle of 80%. The operating temperature range is -40°C to 150°C (TJ).
Packaged in a 16-pin HTSSOP, the TPS54350PWPR is suitable for surface mount applications. Its features include enable, frequency synchronization, power good signal, and internal slow start. The output voltage is protected by peak current limit and thermal shutdown. Applications include industrial and commercial low power systems, LCD monitors and TVs, computer peripherals, and point-of-load regulation for DSPs, FPGAs, ASICs, and microprocessors.
