Designing with the TPS54311 Through TPS54316 Synchronous Buck Regulators

The SWIFT TPS5431x family of internally compensated syncrhounsou buck regulators offers a quick and easy solution to many power supply applications. These devices require a minimum of six additional components. The simple design procedure can be accomplished with the five basic steps outlined in this application note. Devices in this product family include the TPS54311, TPS54312, TPS54313, TPS54314, TPS54315, and TPS54316. These devices can deliver a 3 A of continuous output current from an input voltage of 3 V to 6 V. The output voltage of these devices is fixed by the internal circuitry, and is available in 0.9-V, 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V options.
