TPS62821 - Texas Instruments

TPS62821 Step-Down Converter

The TPS6282x is an all-purpose and easy to use synchronous step-down DC-DC converter with a very low quiescent current of only 4 µA. It supplies up to 3A output current (TPS62823) from a 2.4-V to 5.5-V 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 .
