Productos<\/h2>\n

The TPS543C20RVFT is a 4V to 14V input, 40A synchronous step-down SWIFT converter from Texas Instruments, packaged in a 40-pin LQFN-CLIP (RVF) 5 \u00d7 7 mm package. It features internally compensated advanced current-mode control with adaptive internal compensation, integrated 3 m\u03a9\/0.9 m\u03a9 stacked NexFET power stage, and stackable architecture allowing two devices to deliver up to 80A with current sharing and clock synchronization.<\/p>\n
