TPS54312-Q1

illustrate

As a family member of the DC/DC regulated SWIFT family, TPS54311, TPS54312, TPS54313, TPS54314, TPS54315 and TPS54316 low input voltage high output current synchronous buck PWM converters integrate 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 TPS54311, TPS54312, TPS54313, TPS54314, TPS54315, and TPS54316 devices offer thermally enhanced 20-pin TSSOP (Public Works) PowerPAD™ packages, eliminating bulky heatsinks.
