LM25143/LM25143-Q1 Dual Buck DC/DC Controller Texas Instruments LM25143/LM25143-Q1 Dual Synchronous Buck DC/DC Controller is derived from a family of wide-VIN range controllers ideal for high-current single or dual outputs. The LM25143 utilizes an interleaved, stackable, peak current-mode control architecture for easy loop compensation, fast transient response, excellent load and line regulation, and accurate current sharing with paralleled phases for higher output current. Large step-down ratios provided by the high side switch (with a minimum on-time of 65ns) enable direct conversion from 12V or 24V inputs to low-voltage rails for reduced system complexity and cost.
