Product details

What this regulator brings to the rail

The Texas Instruments TPS622316DRYT is a synchronous step-down (buck) regulator delivering a fixed 2.7 V output at up to 500 mA from a 2.05 V to 6 V input. Its 3 MHz switching frequency lets you shrink the inductor and output capacitors to fit tight PCB layouts — think handheld instruments, IoT edge nodes, or battery-powered modules where every mm² counts.

Package and footprint realities

This part comes in a 6-UFDFN (6-SON) package measuring 1.45 x 1 mm. The exposed thermal pad underneath is the main heat path; your PCB layout must include a thermal via array to the ground plane.

For volume production, qualify the alternate now: the LM53625LQURNLRQ1 is an automotive-grade (AEC-Q100) synchronous buck with 2.5 A output and 2.1 MHz switching — a higher-current sibling if your rail budget grows, though the package and pinout differ. No direct pin-compatible second source exists for the 6-SON footprint, so dual-sourcing means qualifying a different layout.

Frequently asked questions

What is the difference between TPS622316DRYT and TPS622317DRYT?

The TPS622316DRYT outputs a fixed 2.7 V; the TPS622317DRYT outputs a fixed 1.8 V. Both share the same 6-SON package, 500 mA rating, 3 MHz switching, and 2.05-6 V input range. The choice comes down to which fixed output voltage your rail needs.

Can TPS622316DRYT be used with a 3.3 V output?

No — this part outputs a fixed 2.7 V. For a 3.3 V fixed output, look at the TPS622317DRYT (1.8 V) or other members of the TPS6223x family with the desired voltage option.

What is the recommended operating input voltage for TPS622316DRYT?

The input voltage range is 2.05 V minimum to 6 V maximum. For best efficiency, stay within 2.5 V to 5.5 V — the 3 MHz switching maintains regulation across the full range.

Is TPS622316DRYT pin compatible with TPS622317DRYT?

Yes — both parts use the same 6-SON (1.45x1) package and pinout. The only difference is the fixed output voltage (2.7 V vs 1.8 V), so they are drop-in interchangeable on the same PCB layout.
