●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.
