Texas Instruments TPS62825

Beschreibung

The TPS6282x is an ease-to-use synchronous stepdown DC-DC converters family with a very low quiescent current of only 4 μA. Based on the DCS-Control™ topology, it provides a fast transient response. The internal reference allows to regulate the output voltage down to 0.6 V with a high feedback voltage accuracy of 1% over the junction temperature range of –40°C to 125°C. The whole pin-to-pin and BOM-to-BOM compatible device family can be used with a small 470-nH inductor to deliver a scalable 2-A to 3-A power supply solution. The TPS6282x includes an automatically entered power save mode to maintain high efficiency down to very light loads for extending the system battery runtime. 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 short circuit protection as well as a thermal shutdown. The device is available in a 6-pin 1.5 x 1.5-mm QFN package, offering the highest power density solution.
