TPS82672 MicroSiP™ Step-Down Converter

Texas Instruments' TPS82672 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.

The TPS82672 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.
