Description
General part information
TPS62821 Series
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 0.6 V with a high feedback voltage accuracy of 1% over the junction temperature range of -40°C to 125°C. The 1-A, 2-A, 3-A scalable pin-to-pin and BOM-to-BOM compatible device family can be used with small 470-nH inductors.
The TPS6282x include an automatically entered power save mode to maintain high efficiency down to very light loads.
