TPS54620RHLT is a Texas Instruments TPS54620 6 A synchronous SWIFT step-down converter in 14-pin VQFN (3.5 × 3.5 mm, RHL), 250-piece small reel — 4.5 V to 17 V input, adjustable 0.8 V to 15 V output, 200 kHz to 1.6 MHz switching, current-mode control, integrated high-side and low-side MOSFETs, power-good output, enable with tracking and pre-bias startup, −40 °C to +150 °C junction. The RHLT code is the selection point: the RHL package drawing on 250-piece reel — the prototype and pilot-run code that lets you prove the 6 A thermal design before committing to a 3000-piece reel. Selection advice: qualify on the RHLT, then move to the RHLR large reel for production with zero layout change — same RHL drawing, same pinout. Do not substitute the RGY codes without checking the package drawing; RHL and RGY are different TI drawings. The 0.8 V minimum output covers sub-1 V FPGA and DSP core rails directly. Evidence: TI TPS54620 datasheet (Rev. F) package addendum confirms RHL 14-VQFN, 250-piece reel, 6 A and 4.5–17 V. Match the full TPS54620RHLT code.
Ordering-code highlights reviewed against official manufacturer documentation.
TPS54620 is available in the following manufacturer order codes. They share the same TPS54620 design; the table highlights package, packing and ordering differences. Quote the exact code your BOM needs.
| Order code | Package | Packing | Key difference |
|---|---|---|---|
| TPS54620RGYR | VQFN-14 | — | — |
| TPS54620RGYT | VQFN-14 | SMALL T&R | Same VQFN-14 package as TPS54620RGYR; this difference alone does not require PCB pad changes; factory packing is SMALL T&R, 250 per pack; TPS54620RGYR is LARGE T&R, 3,000 per pack. |
| TPS54620RHLR | VQFN-14 | LARGE T&R | Package/pins: VQFN (RHL), 14 pins; TPS54620RGYR is VQFN (RGY), 14 pins; do not assume direct replacement — verify PCB pads, thermal and pinoutt. |
| TPS54620RHLT | VQFN-14 | SMALL T&R | Package/pins: VQFN (RHL), 14 pins; TPS54620RGYR is VQFN (RGY), 14 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; factory packing is SMALL T&R, 250 per pack; TPS54620RGYR is LARGE T&R, 3,000 per pack. |

Browse existing catalog records — same series first, then the same category and manufacturer. These are not confirmed replacements; compatibility requires engineering review.
These are order-code variants of the same Texas Instruments series. They share the core design; the ordering code selects the exact configuration — TPS54620RGYR (VQFN-14); TPS54620RGYT: Same VQFN-14 package as TPS54620RGYR; this difference alone does not require PCB pad changes; factory packing is SMALL T&R, 250 per pack; TPS54620RGYR is LARGE T&R, 3,000 per pack.; TPS54620RHLR: Package/pins: VQFN (RHL), 14 pins; TPS54620RGYR is VQFN (RGY), 14 pins; do not assume direct replacement — verify PCB pads, thermal and pinoutt.. TPS54620RHLT itself is the VQFN-14 configuration. A code that differs by even one character may be a different device, so always quote the complete code exactly as it appears on your BOM.
From the verified technical profile: Package code: VQFN (RHL); Pin count: 14; Operating temperature: -40 to 150 °C. These are the catalog-recorded values for TPS54620RHLT — always re-check them against the manufacturer datasheet revision quoted on your BOM before finalizing the design.
