The TPS54386PWPR is a dual-output, non-synchronous buck converter designed for applications requiring up to 3 A of output current. It operates within an input voltage range of 4.5 V to 28 V and can provide output voltages from 0.8 V to 90% of the input voltage. The device features a fixed switching frequency of 600 kHz, which helps minimize external component requirements. It includes integrated high-side MOSFETs with a low on-resistance of 85 m,Ѷ, enhancing efficiency. The TPS54386PWPR supports various startup modes, including ratiometric and sequential startup, and offers three selectable levels of overcurrent protection. Additionally, it has built-in thermal shutdown protection at +148¬8C and an internal soft-start time of 2.1 ms. The device is housed in a 14-pin HTSSOP package, making it suitable for surface mount applications. This product is compliant with halogen-free standards and operates within a temperature range of -40¬8C to 125¬8C. It is a commonly used part with sufficient supply and demand status, making it a reliable choice for engineers looking for a robust voltage regulation solution.
