Product details

Fixed 1.5V rail for core and logic supplies

The TPS62042DGQ from Texas Instruments is a synchronous buck converter that steps down a 2.5V to 6V input to a fixed 1.5V output, delivering up to 1.2A.

Input range and load budget

With a minimum input of 2.5V and a maximum of 6V, this part covers single-cell Li-ion (3.0V to 4.2V), 3.3V, and 5V regulated buses. The 1.2A output current handles moderate loads like MCU core rails, sensor supplies, or low-power RF stages. Derate the current above 85°C ambient per the datasheet's thermal derating curve; the 10-HVSSOP package's exposed pad helps pull heat to the board copper.
