General Description

The RT8297A/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 RT8297A/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.
