The TPS6223X family is a high frequency synchronous step down DC-DC converter optimized for battery powered portable applications. It supports up to 500 mA output current and allows the use of tiny and low cost chip inductors and capacitors.
The TPS6223X family from Texas Instruments provides high‑frequency synchronous step‑down conversion for battery‑powered portable applications. Available in a 1 × 1.5 × 0.6 mm SON package, the devices operate from 2.05 V to 6 V input and deliver fixed output voltages from 1.2 V to 2.5 V.
Key features include a 3 MHz (up to 3.8 MHz) switching frequency, up to 94 % efficiency, 500 mA peak output current, and a Power Save mode that reduces quiescent current to 22 µA. The part can be forced into PWM mode for noise‑sensitive designs and offers excellent PSRR and load regulation, making it suitable as an LDO replacement in portable audio, cell phones, cameras, and low‑power wireless devices.
