RT7259 10A, 24V, 600kHz Step-Down Converter with Synchronou

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.
