TPS40345 25A Synchronous Buck Controllers

Texas Instruments TPS40345 25A Synchronous Buck Controllers provide an input voltage operating range from 3V to 20V, with 600kHz frequency. The device implements a voltage-mode control architecture with input-voltage feed-forward compensation. This feature responds directly to a change in input voltage. Adding to the switching frequency, the frequency spread spectrum (FSS) feature substantially reduces the peak EMI noise creating a smooth path to EMI compliance standards. User-programmable functions included are soft-start, overcurrent protection (OCP) levels, and loop compensation.
