TPS51219RTER

DC DC Switching Controllers Overview

The TPS51219RTER is a synchronous buck controller from the Texas Instruments TPS51219 series, designed for high-performance power management. It operates within an input voltage range of 3 V to 28 V and utilizes a WQFN-16 package for surface-mount installation. The device supports switching frequencies up to 2 MHz and functions reliably across an operating temperature range of -40°C to +85°C. As a dedicated controller rather than a complete regulator, it requires external high-side and low-side MOSFETs to form a complete DC-DC conversion stage.

DC DC Switching Controllers Feature Summary

• Supports wide input voltage ranges suitable for various bus architectures
• Enables compact designs through high-frequency operation capabilities
• Integrates protection mechanisms including overcurrent and thermal shutdown

DC DC Switching Controllers Applications

• Server and workstation motherboard VRMs
• Graphics processing unit (GPU) core voltage regulation
• Central processing unit (CPU) point-of-load conversion

DC DC Switching Controllers Procurement Notes

Verify the specific suffix RTER against the official datasheet to confirm reel packaging and tape specifications. Ensure compatibility with the required external MOSFET selection for the target current load. Confirm that the WQFN-16 footprint matches the PCB layout guidelines provided in the manufacturer's documentation before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component when designing systems requiring independent control of external power stages within a 3 V to 28 V input window. It is appropriate for applications demanding high efficiency at elevated switching frequencies. Consider the thermal performance of the WQFN-16 package relative to the expected ambient conditions and heat dissipation requirements of the host system.

DC DC Switching Controllers Part Context

This part belongs to the TPS51219 family of synchronous buck controllers manufactured by Texas Instruments. These devices are engineered for demanding computing applications where precise voltage regulation and fast transient response are critical. The family focuses on providing robust control loops while allowing designers flexibility in selecting external power components.

DC DC Switching Controllers Replacement Considerations

Consult the official datasheet for direct pin-to-pin compatible alternatives within the same product family. Verify that any substitute maintains the same input voltage range and switching frequency capabilities.
