LM25145 Synchronous Buck DC-DC Controller

Texas Instruments LM25145 Synchronous Buck DC-DC Controller is designed to regulate from a high input voltage source or from an input rail subject to high voltage transients. This feature minimizes the need for external surge suppression components. A high-side switch minimum on-time of 40ns facilitates large step-down ratios, enabling the direct step-down conversion from a 24V nominal input to low-voltage rails for reduced system complexity and solution cost. The LM25145 continues to operate during input voltage dips as low as 6V, at nearly 100% duty cycle if needed. This option makes the device well suited for high-performance industrial control, robotic, datacom, and RF power amplifier applications.
