DescriptionThe TPS6282x is an all-purpose and easy to use synchronous step-down DC-DC converterwith a very low quiescent current of only 4 μA. It supplies up to 3A output current (TPS62823) froma 2.4-V to 5.5-V input voltage. Based on the DCS-Control? topology it provides a fast transientresponse.
The internal reference allows to regulate the output voltage down to 0.6 V with a highfeedback voltage accuracy of 1% over the junction temperature range of -40°C to 125°C. The 1-A,2-A, 3-A scalable pin-to-pin and BOM-to-BOM compatible device family can be used with small 470-nHinductors.
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 mm x 1.5 mm QFN-8 package.
