It drives an external pair of N-channel MOSFETs in a synchronous rectifier configuration, covering the 4.5 V to 6.5 V supply range typical of 5 V intermediate rails in point-of-load designs. ## Supply range, temperature grade, and package fit Control features include enable, frequency control, and power-good flag — the frequency control pin lets the designer adjust the switching frequency with a resistor to avoid beat-frequency noise in multi-rail systems.","metaTitle":"TPS51218DSCT Texas Instruments Buck Controller, D-CAP™","metaDescription":"TPS51218DSCT active step-down controller from TI's D-CAP™ series. 4.5V–6.5V supply, synchronous rectifier, 10-WSON package.
