The RT7272B is a high efficiency, current mode synchronous
step-down DC/DC converter that can deliver up to 3A output current over a wide
input voltage range from 4.5V to 36V. The device integrates a 150mΩ high side
and a 80mΩ low side MOSFET to achieve high conversion efficiency up to 95%. The
current mode control architecture supports fast transient response and simple
compensation circuit.

A cycle-by-cycle current limit function provides protection
against shorted output and an internal soft-start eliminates input current surge
during start-up. The RT7272B provides complete protection functions such as
input under voltage lockout, output under voltage protection, over current
protection and thermal shutdown.

The RT7272B is available in the thermal enhanced SOP-8 (Exposed
Pad) package.
