Overview
SacPower ÖÇÁª´´Ð Preliminary RT7257E 3A, 17V, 340kHz Synchronous Step-Down Converter General Description The RT7257E is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 3A output current from a 4.
5V to 17V input supply.
The RT7257E's current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors.
Cycle-by-cycle current limit provides protection against shorted outputs, and soft-start eliminates input current surge during start-up.
The RT7257E provides thermal shutdown protection.
The low current (<3μA) shutdown mode provides output disconnection, enabling easy powe...
