Texas Instruments introduces the industry's highest density stackable 18-V input 35-A PMBus converter
2024/8/16
Texas Instruments (TI) has introduced the industry's highest density 18V input, 35-A synchronous DC/DC buck converter. This converter provides a fully differential remote voltage sensing and Power management bus (PMBus) to support telemetry. TI's TPS546C23 power converter integrates high-side and low-side MOSFETs in a small-size package that is significantly denser than competing devices. Designers can stack two converters in parallel to deliver up to 70A loads for processors in space-constrained and power-intensive applications in a variety of markets, including wired and wireless communications, enterprise and cloud computing, and data storage systems.
The highly integrated TPS546C23 power converter is 44% denser (amps/mm2) than competing devices. It has a reference voltage accuracy of 0.5% and fully differential remote voltage sensing function, which can meet the voltage accuracy requirements of deep submicron processors. Current Share is able to stack two converters, providing efficiency and excellent thermal performance through the device's single pad, stacked chip, square flat leadless (QFN) package. Read the blog "Stacking PowerStack Encapsulates Current for Higher Power POL".
For output voltage and soft start time, TI also offers the TPS546C20APMBus converter that supports pin shorting. Learn more about TI's full range of converters with PMBus interfaces.
Key features and advantages of TPS546C23:
· Integrated low Rdson power MOSFETs support 35A continuous output current.
On-chip PMBus interface and non-volatile memory simplify power supply design and support customization.
· Facilitate active power management with output current, output voltage and internal mode temperature telemetry supported by PMBus. Read the blog post, "Power Management Bus (PMBus) - What's the Value?"
Voltage control mode with clock frequency synchronization and input feedforward improves electromagnetic interference (EMI)/ noise and responds quickly to input voltage changes. Synchronizing the frequency with the external clock eliminates beat noise and reduces electromagnetic interference (EMI).
TPS546C23 Support and tools
When combined with TI's WEBENCH® online design tool, the TPS546C23 simplifies power conversion and speeds up the power design process
