The RT7272B is a high efficiency, current mode synchronous step-down DC-DC converter capable of delivering up to 3A output current over a wide input voltage range from 4.5V to 36V. It integrates a 150mΩ high-side MOSFET and an 80mΩ low-side MOSFET to achieve conversion efficiency up to 95%. Features include cycle-by-cycle current limit, internal soft-start, input undervoltage lockout, and over-temperature protection.
