Type: Synchronous Buck Converter

TPS54620RGYT General Description

Designed for small, high-efficiency power supply designs, the TPS54620RGYT is a 17-V, 6-A synchronous step-down converter housed in a thermally enhanced 3.50 mm × 3.50 mm QFN package. By integrating high-side and low-side MOSFETs and employing current mode control, this device minimizes component count and reduces footprint, making it ideal for space-constrained applications. The SS/TR pin allows for precise control of the output voltage start-up ramp, enabling standalone or tracking operation, while power sequencing can be easily configured using the enable and open-drain power good pins. The device also features robust protection mechanisms, including cycle-by-cycle current limiting, low-side sourcing and sinking current limits, and thermal shutdown, ensuring reliable and safe operation in a variety of conditions. With its compact size and comprehensive feature set, the TPS54620RGYT offers a compelling solution for demanding power supply designs
