5A, 17V, 340/800kHz Synchronous Step-Down Converter
General Description
The RT7251A/B is a high efficiency, monolithic synchronous step-down DC-DC converter that can operate at 340kHz/800kHz, while delivering up to 1.
5A output current from a 4V to 17V input supply.
The RT7251A/B's current mode architecture allows the transient response to be optimized.
Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up.
Fault conditions also include output under voltage protection, output over voltage protection and thermal shutdown.
The low current (5μA) shutdown mode provides output disconnection, enabling ...
