TPS62821DLCT Product Details

Texas Instruments' 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 3 A 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. The device features a power good signal and an internal soft start circuit. It can operate in 100% mode. For fault protection, it incorporates a HICCUP current limit as well as a thermal shutdown. The TPS6282x are packaged in a 2 mm x 1.5 mm QFN-8 package.<strong>Features:</strong> DCS-Control topology, 26/25 mΩ internal power switches (TPS62823), Up to 3 A output current (TPS62823), Very low quiescent current of 4 µA, Switching frequency of typically 2.2 MHz, 1% feedback voltage accuracy (full temp. range), Enable (EN) and Power Good (PG), Adjustable output voltage from 0.6 V to 4 V, 100% duty-cycle mode, Internal soft-start circuitry, Seamless power save mode transition, Undervoltage lockout, Active output discharge, Cycle-by-cycle current limit, HICCUP short-circuit protection, Overtemperature protection, Create a custom design using the TPS62822 with the WEBENCH® power designer, POL supplies in portable/battery-powered devices, Factory and building automation, Mobile computing, networking cards, Solid state drives, Data terminals, points of sale, Servers, projectors, and printers

Description

The TPS6282x is an all-purpose and easy to use synchronous step-down DC-DC converterwith a very low quiescent current of only 4 μA. It supplies up to 3A output current (TPS62823) froma 2.4-V to 5.5-V input voltage. Based on the DCS-Control? topology it provides a fast transientresponse.

The internal reference allows to regulate the output voltage down to 0.6 V with a highfeedback 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-nHinductors.

The TPS6282x include an automatically entered power save mode to maintain high efficiencydown to very light loads.

The device features a Power Good signal and an internal soft start circuit. It is able tooperate in 100% mode. For fault protection, it incorporates a HICCUP current limit as well as athermal shutdown.

The TPS6282x are packaged in a 2 mm x 1.5 mm QFN-8 package.
