Product details

Fixed 1.15 V rail for core and I/O supplies

The TPS622315DRYT is a synchronous step-down (buck) converter from Texas Instruments that delivers a fixed 1.15 V output at up to 500 mA. It switches at 2 MHz. The input range runs from 2.05 V up to 6 V. The 6-UFDFN package (1.45 mm × 1 mm body) suits compact portable or embedded designs.

Temperature range and environment

Rated for -40°C to 125°C junction temperature, this part fits industrial control, outdoor telecom, and automotive under-hood environments that see wide thermal swings. The synchronous rectifier improves efficiency at light loads, which matters for battery-powered equipment that spends most of its time in standby or low-power states.

Sourcing and lifecycle

The TPS622315DRYT carries an Active product status with ROHS3 compliance, so there is no last-time-buy risk and no end-of-life watch for new designs.

Frequently asked questions

What is the switching frequency of TPS622315DRYT?

It switches at 2 MHz. That frequency allows small inductor and capacitor values, which reduces PCB footprint.

Is TPS622315DRYT obsolete?

No — the product status is Active. There is no end-of-life notice, and the part is suitable for new designs.
