The IR3622A IC integrates a dual synchronous Buck controller, providing a high performance and flexible solution. The IR3622A can be configured as 2-independent outputs or as current shared single output. The current share configuration is ideal for high current applications. The IR3622A enables output tracking and sequencing of multiple rails in either ratiometric or simultaneous fashion. The IR3622A features 180o out of phase operation which reduces the required input/output capacitance and results in lower number of capacitors. The switching frequency is programmable from 200kHz to 600kHz per phase using one external resistor. In addition, IR3622A also allows the switching frequency to be synchronized to an external clock signal.
