The TPS8268x device is a complete DC/DC step-down power supply optimized for small solution size. Included in the package are the switching regulator, inductor and input/output capacitors. Integration of all passive components enables a tiny solution size of only 6.7mm2.

The TPS8268x is based on a high-frequency synchronous step-down dc-dc converter optimized for battery-powered portable applications in which high load currents in a very small solution size and height are required. The TPS8268x is optimized for high efficiency and low output voltage ripple and supports up to 1600-mA load current. With an input voltage range of 2.5-V to 5.5-V, the device supports applications powered by Li-Ion batteries as well as 5-V and 3.3-V rails.

The TPS8268x operates at a 5.5-MHz switching frequency with spread spectrum capability. For noise-sensitive applications, this provides a lower noise regulated output, as well as low noise at the input. The device supports a fixed output voltage, requiring no external feedback network.

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 with the same size.

The TPS8268x is packaged in a compact (2.3mm × 2.9mm) and low profile BGA package suitable for automated assembly by standard surface mount equipment.
