2.5V to 6V input, 1A output — automotive-grade buck
The Texas Instruments TPS62590TDRVRQ1 is a synchronous step-down buck converter rated for 1A continuous output from a 2.5V to 6V input rail. The adjustable output down to 0.75V lets it feed low-voltage core rails directly.
The synchronous rectifier improves efficiency at light loads, reducing thermal stress in sealed enclosures.
Package and footprint — 6-WSON with exposed pad
The 2.25 MHz switching frequency allows a 1 µH inductor and 10 µF output capacitor in the typical application, keeping the total solution area under 20 mm².
The TPS62590TDRVRQ1 is the tape-and-reel ordering code for the 6-WSON variant; the base product number TPS62590 covers the family.
