The TPS563201 is TI's compact and efficient 3A synchronous buck converter, widely used on drone flight controller boards and ESCs to regulate 5V battery rails down to 3.3V or 1.8V for MCU and sensor power. Its tiny SOT-23-6 package, 95% peak efficiency, and minimal BOM make it the go-to power rail IC in Betaflight/ArduPilot FC designs.
