The TPS6282x is an all-purpose and easy to use synchronous step-down DC-DC converter with a very low quiescent current of only 4µA. It supplies up to 3A output current (TPS62823) from a 2.4V to 5.5V input voltage. Based on the DCS-Control™ topology it provides a fast transient response.
The internal reference allows to regulate the output voltage down to 0.6V with a high feedback voltage accuracy of 1% over the junction temperature range of -40°C to 125°C. The 1,2,3A scalable pin-to-pin and BOM-to-BOM compatible device family can be used with small 470nH inductors.
The TPS6282x include an automatically entered power save mode to maintain high efficiency down to very light loads.
The device features a Power Good signal and an internal soft start circuit. It is able to operate in 100% mode. For fault protection, it incorporates a HICCUP current limit as well as a thermal shutdown.
The TPS6282x are packaged in a 2 x 1.5mm QFN-8 package.
