The TPS54550PWPR with Texas Instruments Voltage Regulators - Switching Regulators 4.5 to 20V Input 6A Step Down is a two-phase synchronous step-down DC/DC converter. It is designed to provide an industry-standard solution for applications ranging from high-current point-of-load (POL) conversion to general DC/DC conversion. The device incorporates high-frequency 0.8- to 2-MHz switching operation, allowing for a compact solution, size, and higher efficiency. Its wide input voltage range from 4.5V to 20V supports multiple regulated voltage outputs from 0.6V to 5.5V. The device offers 6A of a continuous-mode output current and can easily provide up to 10A of output current in pulse-skipping mode. The device includes built-in overcurrent protection (OCP), short-circuit protection (SCP), thermal shutdown (TSD) as well as soft-start, external synchronization, and multiple output power sequencing features. Its multi-mode operation, fast transient response, and excellent cross-regulation enable designers to use the TPS54550PWPR to meet various application demands.
