The document describes a product called TPS54620, which is a full-featured 17V, 6A synchronous step-down converter. It features high efficiency, integrated high-side and low-side MOSFETs, adjustable input undervoltage lockout, and support for SwitcherPro™ software tool.
The TPS54620 is a full‑featured synchronous step‑down converter optimized for compact designs. It integrates high‑side and low‑side MOSFETs in a 3.5 mm × 3.5 mm QFN package, providing up to 6 A output current at up to 17 V input. Current‑mode control and a high switching frequency reduce component count and inductor size.
Key features include power‑good output monitoring, adjustable input undervoltage lockout, programmable switching frequency (200 kHz‑1.6 MHz), and thermal shutdown. The device is suited for high‑density distributed power systems, broadband networking, optical communications, and other applications requiring efficient point‑of‑load regulation.
