Product details

2A continuous, 700kHz — the output filter sizing starts here

The TPS54226PWP is a 2A-rated synchronous step-down (buck) converter from TI's SWIFT™ family, using D-CAP2™ control for fast transient response without external compensation. The 700 kHz switching frequency sets the inductor value and output capacitor count: higher frequency shrinks the magnetics but increases switching losses, so the 700 kHz sweet spot balances board area against efficiency for typical 5V and 3.3V rails. The adjustable output goes from 0.76V up to 5.5V — set by an external resistor divider — covering core voltages for FPGAs, ASICs, and MCUs as well as legacy 3.3V logic.

The synchronous rectifier (integrated low-side FET) eliminates the external Schottky diode and improves efficiency at low output voltages — expect 90%+ efficiency at 5V output, dropping at lower Vout due to the fixed FET Rds(on) losses.

Active lifecycle — no PCN watch needed for existing designs

ROHS3 compliance covers EU RoHS exemption categories — no restricted substances above threshold limits.

Frequently asked questions

What is the closest pin-compatible alternative to TPS54226PWP?

The TPS54226PWP uses the proprietary D-CAP2™ control loop and a specific HTSSOP-14 pinout. A functional replacement would require a board layout change — the 14-HTSSOP footprint with exposed pad is shared by other TI SWIFT™ parts, but the control pin assignments differ. Confirm the pinout against the target design before substituting.

What compliance documentation does TI provide for TPS54226PWP?

The part is ROHS3 Compliant, covering EU RoHS Directive 2011/65/EU and its amendments. Texas Instruments also provides material declaration, REACH SVHC disclosure, and a conflict minerals report through their product compliance portal. No UL or IEC certification is listed for this IC.
