Simplified Application Circuit

General Description

The RT7259 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 10A output current from a 4.5V to 24V

input supply. The RT7259'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 RT7259

is synchronizable to an external clock with frequency

ranging from 300kHz to 1.5MHz.

The RT7259 is available in WDFN-14L 4x3package.
