TPS54310-Q1

illustrate

As a family member of the DC/DC regulated SWIFT, TPS54310 low input voltage high output current synchronous step-down PWM converter integrates all the required active ingredients. Among the features listed with the substrate are a true, high-performance, voltage error amplifier that implements undervoltage latching circuitry under transient conditions to prevent start-up until the input voltage is high performance reaches 3 volts, an internal and external slow-setting start-up circuitry to limit inrush current, a power supply good output processor/logic reset is useful, fault signals and power sequencing.

The TPS54310 device uses a thermally enhanced 20-pin TSSOP (Works) PowerPAD™ package, eliminating bulky heat sinks.
