TPS54317

illustrate

As a family member of the DC/DC regulated SWIFT, TPS54317 low input voltage high output current synchronous step-down PWM converter integrates all the required active ingredients. Included in the listed features with the substrate is a true, high-performance, voltage-error amplifier that provides high performance under transient conditions; One undervoltage latching circuit to prevent start-up until the input voltage reaches 3 volts; An internal and external slow-setting start-up circuitry to limit inrush current, and a power-good output processor/logic reset is useful, fault signal, and power sequencing.

The TPS54317 device is available in a thermally enhanced 24-pin QFN (RHF) PowerPAD package, eliminating bulky heat sinks.
