Product details

Key parametrics for BOM fit

The TPS62821DLCT: Rated for 1 A continuous output current with an adjustable output from 0.6 V up to 4 V, the part covers common core and logic supply voltages in a compact footprint. Switching at 2.2 MHz allows the use of small external inductors and capacitors, shrinking the total solution size while keeping switching losses manageable. The integrated synchronous rectifier eliminates the external Schottky diode, improving efficiency at light loads and reducing BOM count.

Housed in an 8-VFDFN package (supplier device package 8-VSON-HR measuring 2x1.5 mm), the part is surface-mount compatible with standard reflow profiles. The exposed thermal pad under the package must be soldered to a PCB copper area for rated thermal performance — layout guidelines from TI recommend a minimum of 4 vias connecting to an internal ground plane.
