The TPS54357PWP from Texas Instruments is a synchronous step-down (buck) DC/DC switching regulator. It integrates a high-side MOSFET and a gate driver for an optional low-side external MOSFET, enabling high efficiency operation.
Key electrical specifications include a continuous output current of 3A, a peak MOSFET switch resistance of 100 mOhm, and a wide input voltage range from 6.5V to 20V. The device provides a fixed 5V output voltage. It operates with selectable switching frequencies of 250 kHz or 500 kHz, or an adjustable range from 250 kHz to 700 kHz.
Designed for ease of use, the TPS54357PWP features internal compensation for a low parts count and includes an internal slow-start circuit to manage in-rush currents. It also offers adjustable undervoltage lockout and load protection through peak current limit and thermal shutdown.
This component is housed in a 16-pin HTSSOP package, suitable for surface mounting. Its applications include industrial and commercial low power systems, LCD monitors and TVs, computer peripherals, and point-of-load regulation for high-performance processors.
