The TPS54316-Q1 uses a 3V to 6V input, 3A synchronous buck converter with a 3.3V output voltage
illustrate
As a family member of DC/DC regulated SWIFT, TPS54311, TPS54312, TPS54313, TPS54314, TPS54315 and TPS54316 low input voltage high output current synchronous step-down PWM convertersintegrate are all necessary active ingredients. Included in the listed features with substrate is a true, high-performance, voltage-error amplifier that provides fast response under transient conditions; an undervoltage lockout circuit to prevent start-up until the input voltage reaches 3 volts; An internal and external slow setup startup circuit to limit inrush current, as well as a power good output processor/logic reset, fault signaling, and power sequencing are useful.
The TPS54311, TPS54312, TPS54313, TPS54314, TPS54315, and TPS54316 device devices are available in thermally enhanced 20-pin TSSOP (Public Service) packages that will be PowerPAD™ packages, eliminating bulky heat sinks.
