® RT7257B 3A, 18V, 1.
2MHz Synchronous Step-Down Converter General Description The RT7257B is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 3A output current from a 4.
5V to 18V input supply.
The RT7257B's current mode architecture and external compensation allow the transient response to be optimized over a wide input voltage range and loads.
Cycle-by-cycle current limit provides protection against shorted outputs, and soft-start eliminates input current surge during start-up.
The RT7257B also provides under voltage protection and thermal shutdown protection.
The low current (3μA) shutdown mode provides output disconnection, enabling easy power m...
