The TPS8267x device is a complete 600mA, DC/DC step-down power supply intended for low-power applications. Included in the package are the switching regulator, inductor and input/output capacitors. No additional components are required to finish the design.
The TPS8267x is based on a high-frequency synchronous step-down dc-dc converter optimized for battery-powered portable applications. The MicroSiP™ DC/DC converter operates at a regulated 5.5-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.
The TPS8267x is packaged in a compact (2.3mm × 2.9mm) and low profile (1.0mm) BGA package suitable for automated assembly by standard surface mount equipment.
