Caution: Stresses above those listed in "Absolute Maximum Rating" may cause permanent damage to the device. These are stress ratings only and function of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to "Absolute Maximum Rating" conditions for extended periods may affect device reliability.
The IR3622MPbF integrates a dual synchronous Buck controller, providing a high performance and flexible solution. The IR3622 can be configured as 2-independent outputs or as current shared single output. The current share configuration is ideal for high current applications.
The IR3622MPbF enables output tracking and sequencing of multiple rails in either ratiometric or simultaneous fashion. The IR3622 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, IR3622 also allows the switching frequency to be synchronized to an external clock signal.
Other key features offered by this IR3622MPbF include two independent programmable soft starts, two independent power good outputs, precision enable input, and under voltage lockout function. The current limit is provided by sensing the lower MOSFET's on-resistance for optimum cost and performance. The output voltages are monitored through dedicated pins to protect against open circuit, and enhance faster response to an overvoltage event.
