Parametric fit for a 500 mA point-of-load rail
The TPS622314DRYR is a fixed 1.5 V output step-down (buck) converter from Texas Instruments, rated for 500 mA continuous output current. The synchronous rectifier eliminates the external Schottky diode, improving efficiency at light loads and simplifying the BOM to one inductor and two capacitors.
Temperature grade and package for industrial deployment
The 125°C junction ceiling gives headroom for self-heating at full load in a 105°C ambient. Housed in a 6-UFDFN (6-SON) package measuring 1.45 mm × 1.0 mm (supplier device package 6-SON), the part fits under a 2 mm keep-out zone on the bottom side of a dense PCB.
Active lifecycle and compliance posture
No single-source risk — the part is widely stocked across multiple TI-authorized distributors.
