Device Overview
TPS62933DRLR is the 8-pin DRL SOT-5X3 orderable of TI’s TPS62933 low-IQ synchronous buck converter. It regulates up to 3 A continuously from a 3.8 V to 30 V input and supports output settings from 0.8 V to 22 V. TI specifies a -40 °C to 150 °C operating junction range for this family.

Engineering Selection Guidance
The TPS62933 combines a broad bus-voltage range with a typical 12 uA quiescent current, which is useful when a system must remain connected to 12 V, 19 V, or 24 V rails without excessive standby draw. The switching frequency is selectable from 200 kHz to 2.2 MHz, allowing the designer to trade magnetic size and switching loss against efficiency and EMI goals. The exact TPS62933 variant provides ECO-mode light-load behavior and adjustable soft start; pin-compatible family variants use different light-load or power-good behaviors, so suffix-level comparison matters. Cycle-by-cycle current limiting, OTP, OVP, UVP, UVLO, and spread-spectrum support address common fault and EMI concerns.
Procurement Notes
Manufacturer lifecycle/status evidence for this exact orderable is recorded as ACTIVE. Package identity is SOT-5X3-8 (DRL). Confirm final availability, lot/date-code requirements, and commercial terms through the RFQ process.
Lifecycle status does not indicate HKEQGOO stock, lead time, MOQ, or final availability.
For a related 3-A buck converter with an out-of-audio operating mode intended to avoid audible switching noise, compare TPS62933ODRLR. The O variant changes light-load operation; check the TI device-specific operating modes rather than assuming both orderables behave identically.
