The Texas Instruments TPS54355PWPR is a synchronous buck PWM converter designed for medium output current applications. It integrates a high-side MOSFET and supports an optional low-side external MOSFET or diode.
Key electrical specifications include a 100 mΩ peak MOSFET switch resistance, enabling high efficiency at 3A continuous output current. The device supports fixed output voltages such as 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V, with an input voltage range of 4.5V to 20V. The PWM frequency can be fixed at 250 kHz or 500 kHz, or adjusted from 250 kHz to 700 kHz.
Features such as internal compensation, synchronization to an external clock (with 180° out-of-phase capability), internal slow start, peak current limit, thermal shutdown, and adjustable undervoltage lockout enhance its design flexibility and protection.
Packaged in a 16-pin HTSSOP with a PowerPAD, the TPS54355PWPR is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C. Applications include industrial and commercial low power systems, LCD monitors and TVs, computer peripherals, and point-of-load regulation for high-performance processors.
