TPS82670 DC/DC Step-Down Regulator

From Evolution to Revolution: Texas Instruments' first fully integrated DC/DC step-down regulator offers the simplicity of a 3-pin regulator at less than 6.7 mm2, with up to 90% efficiency at very low noise. The TPS8267x device is a complete 600 mA, 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.
