Fixed 1.5 V rail for low-power loads
The Texas Instruments TPS62201DBVTG4 is a synchronous step-down (buck) converter that delivers a fixed 1.5 V output from an input range of 2.5 V to 6 V. It is designed for battery-powered or low-voltage rail applications where a single 300 mA output is sufficient. The 1 MHz switching frequency allows the use of small inductors and ceramic capacitors, keeping the total solution footprint compact.
Synchronous rectification and efficiency
The positive output configuration and fixed 1.5 V regulation mean no external feedback divider is required — just the inductor, input/output caps, and the chip.
