TPS54312

illustrate

As a family member of DC/DC regulated SWIFT, TPS54311, TPS54312, TPS54313, TPS54314, TPS54315 and TPS54316 low input voltage high output current synchronous buck PWM convertersintegrate all required active ingredients. Included in the listed features with the substrate is a true, high-performance, voltage-error amplifier that provides fast response under transient conditions; One undervoltage latching circuit to prevent start-up until the input voltage reaches 3 volts; An internal and external slow-setting boot circuitry to limit inrush current, as well as a power-good output processor/logic reset, fault signal and power sequencing are useful.

The TPS54311, TPS54312, TPS54313, TPS54314, TPS54315, and TPS54316 devices offer thermally enhanced 20-pin TSSOPs (Works) to package PowerPAD™, eliminating bulky heatsinks.
