LM5143/LM5143-Q1 Synch Buck DC-DC Controllers

Texas Instruments LM5143/LM5143-Q1 2-phase Synchronous Buck DC-DC Controllers are designed for high-current single or dual outputs. The LM5143/LM5143-Q1 uses an interleaved, stackable, peak current mode control architecture for easy loop compensation, fast transient response, as well as excellent load and line regulation. The device also features accurate current sharing with paralleled phases for higher output current.
