Texas Instruments rolled out what it claims is the industry’s smallest 12 A, synchronous DC-DC buck converter with PMBus interface. The SWIFT TPS53915 converter features a tiny PowerStack QFN package and integrated NexFET MOSFETS to drive ASICs in space-constrained and power-dense applications in a variety of markets, including wired and wireless communications, enterprise/cloud computing and storage systems.
Used in conjunction with TI’s WEBENCH online design tools, the device can simplify power conversion and speed the design process. It features 0,5% reference voltage accuracy to meet the voltage requirements of deep sub-micron processors.
D-CAP3 adaptive on-time control mode is easy to use, provides very fast load transient response and reduces external component count. Programmability and fault reporting via PMBus simplify power supply design and further reduce component count. Other features include no external compensation, internal soft start, input under-voltage protection, internal bootstrap capacitor and thermal shutdown.
For analog applications without PMBus control, TI offers the SWIFT 8 A TPS53513 and 12 A TPS53515 pin-to-pin compatible buck converters.
