TPS546B26 Synchronous Buck Converter

Texas Instruments TPS546B26 Synchronous Buck Converter offers PMBus^®, telemetry, and D-CAP4 control topology for fast transient response. The PMBus configured all the programmable parameters and stored them in NVM as the new default values to minimize the external component count. The TPS546B26 buck converter features a 4V to 18V input voltage range without external bias and a 2.7V to 18V input voltage range with external bias. This converter supports 25A single-phase, a 400kHz to 2MHz operating frequency range, a 0.4V to 5.5V output voltage range, and a 0.5ms to 16ms programmable soft-start time. The TPS546B26 buck converter is a lead-free device and RoHS compliant without exemption. Typical applications include server and cloud-computing POLs, hardware accelerators, and network interface cards.
