LMQ644xx-Q1 36V Synchronous Buck DC-DC Converters

Texas Instrument LMQ644xx-Q1 36V Synchronous Buck DC-DC Converters are designed for high-current single or dual outputs. The device uses an interleaved, stackable, current-mode control architecture for a fast transient response, easy loop compensation, line regulation, excellent load, and accurate current sharing with an output clock supporting up to six phases for currents up to 36A. A high-side switch minimum on-time of 50ns gives large step-down ratios, enabling the direct conversion from 12V, 24V, or automotive inputs to low-voltage rails for reduced system complexity and design cost.
