® RT8298A 6A, 24V, 600kHz Step-Down Converter with Synchronous Gate Driver General Description The RT8298A is a synchronous step-down DC/DC converter with an integrated high side internal power MOSFET and a gate driver for a low side external power MOSFET. It can deliver up to 6A output current from a 4.5V to 24V input supply. The RT8298A's current mode architecture allows the transient response to be optimized over a wider input voltage and load range. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up. The RT8298A is synchronizable to an external clock with frequency ranging from 300kHz to 1.5MHz. The RT8298A is available in SOP-8 (Exposed Pad) packages.
