General Description
The RT7272A 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 RT7272A provides complete protection functions such as input under voltage lockout， output under voltage protection， over current protection and thermal shutdown.
The RT7272A is available in the thermal enhanced SOP-8 （Exposed Pad） package.
