Synchronous step-down regulator provides one adjustable buck output for power conversion from a wide input supply. The output voltage range is 0.97 V to 41.5 V with up to 6 A output current. The switching frequency range is 200 kHz to 3 MHz, and spread-spectrum operation supports low-EMI designs. The device uses a 24-lead exposed-pad TFQFN/LQFN package and operates from -40 °C to +125 °C.
