Product details

3.3 V fixed rail at 1.6 A — 3 MHz keeps the inductor small

The TPS62063DSGR: The 3 MHz switching frequency shrinks the inductor to a 1 µH to 2.2 µH footprint — critical when the board area is the constraint, not the efficiency curve at full load.

Synchronous rectification — the external Schottky stays off the BOM

The integrated synchronous rectifier eliminates the catch diode, saving one component and the associated forward-drop loss. At light loads the part enters power-save mode; the switching frequency drops to maintain regulation without excessive ripple. The fixed 3.3 V output means no feedback divider — the FB pin is internally set, so the resistor pair is zero parts on the BOM.

8-WSON (2x2 mm) — thermal path through the exposed pad

Frequently asked questions

Is TPS62063DSGR compatible with my existing 3.3 V design?

The synchronous rectifier and 3 MHz switching frequency mean the external component count is low — typically one inductor, two ceramic caps, and no Schottky diode.
