The TPS6267x devices are high-frequency synchronous step-down dc-dc converters optimized for small battery-powered applications. Intended for low-power applications, the TPS6267x supports up to 650-mA load current and allows the use of low cost chip inductor and capacitors.

With a wide input voltage range of 2.3V to 4.8V, the device supports applications powered by Li-Ion batteries with extended voltage range. Different fixed voltage output versions are available from 1.05V to 2.1V. The TPS6267x operates at a regulated 6-MHz switching frequency and enters the power-save mode operation at light load currents to maintain high efficiency over the entire load current range.

The PFM mode extends the battery life by reducing the quiescent current to 17µA (typ) during light load operation. For noise-sensitive applications, the device has PWM spread spectrum capability providing a lower noise regulated output, as well as low noise at the input. These features, combined with high PSRR and AC load regulation performance, make this device suitable to replace a linear regulator to obtain better power conversion efficiency.
