Product details

1.5 A synchronous buck — the fixed 5 V rail you can count on

The TPS62112RSARG4 is a synchronous step-down (buck) regulator from Texas Instruments, delivering a fixed 5 V output at up to 1.5 A from an input range of 3.1 V to 17 V. It switches at 1 MHz, which keeps the inductor small and the output ripple manageable for a 5 V rail powering MCUs, sensors, or small logic loads.

Fixed 5 V — no divider, no trim pot

Because the output type is fixed at 5 V, there is no feedback divider to populate or tolerance stack to manage.
