Stackable 18-V input, 35-A PMBus converter delivers industry's highest density

TI's DC/DC buck converter features remote voltage sensing and supports telemetry

DALLAS, Dec. 7, 2016 — (PRNewswire) —  Texas Instruments (TI) (NASDAQ: TXN) today introduced the industry's highest-density, 18-V input, 35-A synchronous DC/DC buck converter, which offers full differential remote-voltage sensing and PMBus to support telemetry. TI's TPS546C23 power converter integrates high- and low-side MOSFETs into a small-footprint package that is significantly denser than competitive devices. Designers can stack two converters in parallel to drive loads up to 70 A for processors in space-constrained and power-dense applications in various markets, including wired and wireless communications, enterprise and cloud computing, and data storage systems. For more information, samples and an evaluation module, see www.ti.com/tps546C23-pr.

The TPS546C23 from Texas Instruments is a high-density, 18-V input, 35-A synchronous DC/DC buck converter with full differential remote-voltage sensing and PMBus to support telemetry. The power converter integrates high- and low-side MOSFETs into a small-footprint package that is significantly denser than competitive devices. Designers can stack two converters in parallel to drive loads up to 70 A for processors in space-constrained and power-dense applications in various markets, including wired and wireless communications, enterprise and cloud computing, and data storage systems.

The highly integrated TPS546C23 power converter is 44-percent denser (amperes per square millimeter) than competitive devices. It features 0.5 percent reference-voltage accuracy over temperature and full differential remote-voltage sensing to meet the voltage accuracy requirements of deep sub-micron processors. Current sharing enables the stacking of two converters and high efficiency and excellent thermal performance are delivered via the device's single-pad, stacked die, quad flat no-lead (QFN) package.

TI also offers the TPS546C20A PMBus converter that supports pin-strapping for both the output voltage and soft-start time. Get more information on TI's entire portfolio of converters with the PMBus interface.
