Product details

2A synchronous buck with fixed 1.8V rail

The TPS6209718RWKT is a 2A synchronous step-down converter from Texas Instruments, part of the iDCS-Control series, delivering a fixed 1.8V output from a 2.5V to 6V input bus. The synchronous rectifier keeps efficiency high across the load range, and the 1.5MHz to 2.5MHz switching frequency allows small external inductors and capacitors — useful for space-constrained designs like portable equipment, wireless modules, or industrial sensors.

Package and thermal: 11-VFQFN-HR (2x2 mm)

The 2A continuous rating is derated above 85°C ambient depending on board copper area and airflow.
