TPS62825A - Texas Instruments

TPS62825A Step-Down Converter

The TPS6282x is an easy-to-use, synchronous stepdown DC/DC converters family with a very low quiescent current of only 4μA. Based on the DCSControl topology, the device 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 .
