Texas Instruments TPS6282x Step-Down Converters are all-purpose and easy to use synchronous step-down DC-DC converters with a very low quiescent current of only 4µA. These devices supply up to 3A output current (TPS62823) from a 2.4V to 5.5V input voltage. Based on the DCS-Control™ topology the TPS6282x 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 can be used with small 470nH inductors.
