Texas Instruments 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.
The TPS546C23 integrates high- and low-side MOSFETs into a small-footprint package. 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 power converter features 0,5% 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.
