1A buck with DCS-Control — why the switching frequency matters
The TPS62160DSGT is a 1A step-down buck regulator from Texas Instruments' DCS-Control series, switching at 2.25 MHz.
Adjustable output from 0.9V to 6V — input range 3V to 17V
Input range spans 3V to 17V, so it handles 5V and 12V rails cleanly. The synchronous rectifier is on-chip — no external Schottky diode needed, which saves board space and BOM cost.
8-WSON package — rework and layout notes
The 8-WFDFN exposed pad (2x2 mm body) is a small QFN-style package. Under a hot-air station, the part lifts cleanly if the board is preheated to 150°C; the small pad area means it reflows quickly.
