Texas Instruments  TPS62821DLCR

The TPS6282x is an all-purpose and easy to use synchronous step-down DC-DC converterwith a very low quiescent current of only 4µA. It supplies up to 3A output current (TPS62823) froma 2.4V to 5.5V input voltage. Based on the DCS-Control™ topology it provides a fast transientresponse.

The internal reference allows to regulate the output voltage down to 0.6V with a highfeedback voltage accuracy of 1% over the junction temperature range of -40°C to 125°C. The 1,2,3Ascalable pin-to-pin and BOM-to-BOM compatible device family can be used with small 470nHinductors.

The TPS6282x include an automatically entered power save mode to maintain high efficiencydown to very light loads.

The device features a Power Good signal and an internal soft start circuit. It is able tooperate in 100% mode. For fault protection, it incorporates a HICCUP current limit as well as athermal shutdown.

The TPS6282x are packaged in a 2 x 1.5mm QFN-8 package.
