The IRU3146 IC is a Dual synchronous Buck controller, providing a cost-effective, high performance and flexible solution. The IRU3146 can be configured as a 2-independent or as a 2-phase controller. The 2-phase configuration is ideal for high current applications. The IRU3146 features 1808 out of phase operation which reduces the required input/output capacitance and results in a fewer number of capacitors needed. Other key features offered by this device include two independent programmable soft starts, programmable switching frequency up to 400KHz per phase, Hiccup current limit and an under voltage lockout function. The current limit is provided by sensing the lower MOSFET's on-resistance for optimum cost and performance. |
