Description
The RT9220PQV is a high-speed switching controller designed for use in synchronous DC/DC buck converters for modern CPUs. It provides a regulated output voltage that is digitally programmable from 1.3V to 3.5V with an initial accuracy of ±1%. This model drives two external N-channel MOSFETs, resulting in high efficiency and eliminating the need for expensive P-channel devices. It also features an adjustable current limit without the need for an external sense resistor, as it senses the output current across the on-resistance of the upper N-channel MOSFET.
